I think the vast majority of households do not know or care about sharpening their knives. The industrial solution has been to make serrated blades which cut better over a longer time. They make them cheap so you can just throw them away and buy a new one. I remember sharpening up my mother's kitchen knives with my newly acquired sharpening skills; she promptly cut herself and chastised me for making them too sharp. LOL

True, most of my friends and acquaintances I go to to cook together have dull knives in their kitchen, so the first thing I do is to grab a ceramic coffee cup and sharpen the chef knife on its bottom side. And yes, most people are not used to sharp knives, and my mom has cut herself also multiple times on my (sharp) kitchen knives, she's never cut herself with dull kitchen knives. As someone said here, dull knives are not necessarily more dangerous than sharp knives. It depends on your expectations and how you handle them.

They actually make a "safety" ceramic knifes for cardboard and paper. Instead of a perfectly sharp edge they jave a microscopically rounded over edge. it wont cut skin but it cuts cardboard no problem. The rounded edge also significantly helps prevent the micro chipping. The ceramic utility kife blades last easily a few years in a wearhouse where we cutup a dozen boxes a day.

I was at a friend's barbecue many years ago where I pitched in to help prepare the food. I found all of their knives so dull they were almost useless. I asked if they had any type of knife sharpening tools. Nope. As I was standing there in the kitchen drinking my coffee I looked at the ceramic coffee cup in my hand and got an idea. I finished the coffee in a gulp, rinsed out the cup, turned it over and used the the rough rim around the bottom of the cup like a sharpening stone. In short order I was able to sharpen all of their knives using the cups in their cupboard. Not perfect, but in a pinch...a DIY sharpener.

Regarding ingesting ceramic / metal dust, I think no one ought to be worried about this. Normal dust that's in the air and on every surface is composed of lots of things, but in large part it is silica - quartz. Very hard and potentially sharp. And we breathe it and eat it all day long. It's pretty near unavoidable. Is it great to breathe in dust all day? No, but we produce mucus for a reason. How much ceramic dust is getting in your food from using ceramic knives? I'm guessing it's not significant. Thanks for this follow up video, BTW. Really interesting and useful!

Kyocera tends to be top shelf quality along with kissing crane. I have a black zirconium ceramic that I paid $200 dollars for over 30 years ago and it’s still my go-to blade for fish and other seafood. Cuisinart, on the other hand, is pure junk. You know, the ones I let the wife use, because it just doesn’t matter if she breaks or chips one. They’re fine for veggies and soft food. They aren’t for carrots or cabbage mind you, but most other stuff. I have German and Japanese blades in varying steel types and I use shapton stones for them. I love my steel blades but I don’t think I’ll ever be without some ceramic.

My aunt gave me a ceramic knife and potato peller about twenty years ago. The knife still cuts pretty well but the real star is the potato peeler. Of course, I don't use it that often but it's still sharper than any steel peeler and most of the steel peeler's I've ever used couldn't be taken apart to sharpen (not that I would at $5 a pop anyway) so in this case it's ceramic for the win. I think in a throw away home ceramics are superior because they are typically sharper out of the box and stay that way longer and when knives get dull most households just trow them out and get new ones anyway. In a household where someone is will to sharpen the knives regularly then a good steel knife is better long term.

the flavor transfer is a thing. the problem is most people dont have a good enough palate to taste it. but if you ask a high end chef, especially a chef who uses carbon steel knives, there is a slight taste of sulfur transferred from that. also carbon steel will stain food like onions if you take long pauses between cutting. but i suppose its just the oxidation coming off the surface of the steel, and typically this only happens between the new knife and building a patina stages of carbon steel knives

That said, after maybe 5 years of rough home kitchen usage the "where did those chips go?" does become concerning. If you respect the tool and keep that in mind / don't use a non-cleaver as a cleaver or with metal forks or skewers you can ding into if incautious, worthy investment, and nice if there's some way to recycle scrapped kitchen blades into utility knives. My experience is out of date, so I imagine there's a lot of good manufacturers now and my generics still wow'd for standard cutlery table knife prices, but would figure name brand hopefully still gets you the best edge possible as you probably won't be messing with if you're just cooking at home.

I bought a retractable ceramic blade knife years ago for cutting vinyl shelf paper. I had installed new vinyl as some of them I had put in had begun to tear. It worked great but I was always worried about dropping it and breaking it. A friend moved and I offered to do all her cabinets as she shelf paper in her current house. She bought the rolls of vinyl and it took many hours because she had a LOT of cabinets including built in desks with drawers in the bedrooms and study. Literally every room in the large house has cabinets and/or drawers. The knife never dulled. I still keep it in my kitchen drawer and use it to open boxes, packages or bags and often wondered if I should sharpen it. I do sharpen my steel knives as I have arthritis and don’t have much hand strength. I have gone to friends homes and can’t believe how many dull knives and warped pans people use when I have helped them and struggled to cut or cook anything. The only serrated knife I have is a bread knife which has retained it’s edge since most purchased items are pre sliced or can be sliced by the bakery if asked. Why struggle with something that doesn’t take much time to keep or put an edge on a knife. I sew and used to have an older gentleman drive through the neighborhood and sharpen knives and scissors. He was wonderful at getting my scissors sharpened and properly tightened. I don’t think anyone goes door to door with this anymore and probably why so many people just use dull knives.

Chef for over 3 decades, here. My 2 cents worth, ceramics are okay for the home. In a production kitchen, a ceramic blade is going to break, or shatter. It's not "if" it will be ruined, it's "when". As far as oxidation of fruits and veggies, a somewhat dull steel blade may cause slightly quicker oxidation than a ceramic, but, a properly sharpened plain-edged (non-serrated) steel knife does the best job. For leafy things, like the various lettuces, greens, cabbages, once again, a properly sharp steel blade is good, but, a cheap, plastic "lettuce knife" will do a better job, than anything, and ceramic does a good job. The plastic "lettuce knives" wear out faster than either steel or ceramic, and you can't really sharpen them, but they are, usually, cheap. After all that, my recommendation is, get a good steel knife and learn to properly sharpen, and maintain, it. I'm sure their are plenty of "pros" out there, who would disagree, but that is the nature of Culinary Arts.

Thanks. I now understand why I was able to sharpen that ceramic knife on my Tormek SG-250 wheel. I followed the factory bevel angle which must have been quite obtuse. Some punters laughed at me and said "it's full of chips" but I looked at it very close with a jeweller's loupe and couldn't see any chips. It looked like a regular good sharp edge and it sliced through paper far better than it did before I sharpened it (it was visibly chipped) although I didn't test it with delicate cigarette paper (17gsm). After watching this I now want to run further tests but I don't own one and have to wait for a customer to ask again. Still, great knowledge imparted. Thanks. Great work. Mystery solved.

I found one of the black ceramic ones inside a tool box i got at an auction. It was chipped, so i cut a strip out of it (about 3mm all the way) and sharpened one sided (akin to a Japanese knife) it with deep grooves. Been using it for almost 10 years now and it hasn't chipped or lost its edge. I used a diamond wheel to do the work - took about 40 minutes to sharpen the thing because i was working under water. Honestly, if it's not a cheapy and it's a thick blade, they're ok knives. The fact that i didn't need to sharpen it all this time, that's a solid 10/10 for me.

It makes total sense, as a sharp knife will cut much more cleanly through the food and reduce the amount of surface area exposed to the air. A dull knife that tears at the food will certainly cause pieces to stick out, increasing surface area exposed to air. And your sense of humor is awesome, keep up the great work!

Your ceramic knife is decidedly inferior because the handle is just too small and the blade is 30pc thinner so it shatters when dropped. ALDI ceramic knives have far better larger handles and are 30pc THICKER and don't shatter when dropped and the points take many years to chip ( where its thinner) So graduate to ALDI ceramic knives to improve your life.

Great vid as always. The thing that sticks out in my mind is that the first knives man ever used were made out of stone, which I guess is more silica than ceramic. Either way though, the sharpening is kiiiiind of similar? Those old stone and flint knives were sharpened via chipping. The right kind of chipping gave you a very sharp edge, in some cases an edge that still holds up today (Flint). Hmmm, actually it's more like chipping was used for sharpness in the old stone knives, but has the opposite effect here. Ugh, never mind, move along.

Meaning I swallowed these micro chips and there passing through my digestive system. These damn things should be outlawed. Lucky me they passed through without slicing my intestines open. These blades shatter way to easily and should be avoided for food products. Some of the chips where 1/32 of an inch in size.

@conorstewart2214Ай бұрын
You are totally right that the majority of people do not have sharp knives at home and have likely never thought about sharpening. Most don’t know how to use knives well either. I am no chef outside of what I cook for myself but watching other people try and cut food is just painful, something that with minimal technique would take 10-20 seconds I have seen take up to 5 minutes for some people. People just don’t know how to handle knives, they are slow, inefficient and treat them like they are dangerous and then go and do stupid stuff. Just like any other tool the only thing dangerous about a knife is the person. Learn how to actually control what your hands are doing and be careful and you will be fine with even very sharp knives. People that do think about sharpening often aren’t much better, especially if they just buy a cheap sharpening tool (like the ones that you pull the knife through) or one of those sticks they see professional chefs using. Now both of those types of tools if done well are fine for sharpening but in a home kitchen they just aren’t. I have seen pull through sharpeners that didn’t actually sharpen the knife, it just put micro serrations on it and made it harder to properly sharpen. All most knives need is a few minutes on a stone every so often, maybe a little longer if it has been left a while or been abused. The only knives that consistently take me longer are a couple of old dark Sabatier knives, definitely not stainless, rusts very quick (leave it wet at all even just for half an hour and there will be some rust) and the knife other than the edge is dull and dark rather than shiny. The knives take a while to sharpen but they stay sharp for a long time too and I seem to be able to get them sharper, great knives just not stainless. I have no idea what kind of steel it is.

My dad was a 3rd generation master shear and knife craftsman from Solingen Germany, where Wushöf are made. I was lucky enough to be taught the ins and outs of blades (oh god pun not intended). He sharpened knives perfectly. He actually helped their business partners in Japan develop a ceramic hair cutting scissor! So he also worked with ceramics, so he knew what you discovered here. He told me almost the exact same knowledge! It’s the grain by the way. Ceramic doesn’t have grain, steel does. It’s the microscopic structure of this grain that allows you to sharpen it to a hair whittling edge. Ceramic will hold longer but it’s far more brittle and if you try to get it to the same sharpness of your steel it will chip. Grain and grain direction is incredibly important when making steel knives. And though I’m eternally grateful to pops, God rest his soul, I now walk this earth with the curse of watching how almost every single person mistreats their blades, and thinks knives are consumable and have to be replaced. A good blade with proper care will last you a lifetime. Thank you for sharing this knowledge. Everyone, you will spend far more money on cheap knives and scissors in your life than if you just save up for a good knife. Unless it’s completely destroyed somehow, you will have it forever. If you don’t want to learn how to sharpen yourself, take it to be sharpened by a professional. It isn’t too expensive. Even with routine sharpening you’ll still be paying less than continually buying crappy knives. And DONT PUT YOUR KNIVES IN THE SINK, FOR THE LOVE OF GOD

I like how up close the ceramic blade looks like ice. Also, I work at Walmart stocking and with a normal razor blade I'd change it out after like 3 months. The actual razor blade itself though gets dull after a few weeks, slicing through stuff packaged in think plastic or cutting through shrink wrap will show that. I just usually use more force but eventually I need a new one. Then I got a ceramic box cutter and that ceramic blade has lasted me two years before it broke (when I was being careless, it would have lasted longer). It was amazing just how long it stayed sharp when used properly and with a good application.

Yes, yes, steel knives are really good, if you sharpen them regularly and good at sharpening them, but most people are not. Most "off the shelf" knife sharpeners are basically useless junk, so many household can't ever sharpen their knives to even the same level as new ones (let alone a shaving edge). Ceramic knives are for them. They remain usable basically for infinity (even if they lose some of their initial sharpness), if you take care of them. And that's all your average joe really needs.

NIce, I'm running to the Dollar store immediately to get one of these cheap ceramic knifes. We now use Stanley (and other brand) utility blades to cut cardboard boxes to size for re-use or to put them in our recycling container but we all know that a dulling blade takes more force and that results in increased chance for accidents. Even the original Stanley blades wear out within one busy day so if I get more use out of a cheap ceramic knife and if that increases safety then that is surely worth it - even if I cannot sharpen the blade and use those knifes as a disposable one.

But the fact of the fruit turning dark isn't about stainless steel knives, it's about carbon steel knives! Carbon steel leaves a taste behind on fruit and veggies and will turn an apple dark because of the composition of the blade. My dad used Old Hickory brand knives religiously until they wore slap out. After I cut an apple up with the ceramic knife he asked if I was going to get a bigger one! Which I did later for the tune of about $159. I also have stainless steel knives because I was always afraid of dropping the ceramic and it shattering (which has never happened).

Thanks for the video - it was very informative! A couple of observations (I'm not an expert but these worth looking into): although metals might not play much role in oxidation of the food, amino-acids and other compounds in the food might react to metal in the knives. This is less of a case for stainless steel knives, but nevertheless there's a very slight influence on a taste. Although majority of us will never tell the difference. Second point is about chips in the food: our digestive tract is has a very agressive conditions inside. If microscopic metal chips are introduced, I assume, those chips get dissolved or at least covered in salts, as a result of chemical reactions. Whereas ceramic is almost inert and doesn't react with anything in our body. Although, from what I read, if the chips are not visible (i.e. small enough) they can pass through the digestive system without causing harm.

Several years ago now, I made a ceramic and carbon fiber laminate straight razor. It was deeply terrifying to shave with, but shaving with it was entirely doable. Part of the trick for a more durable edge is indeed to take the edge up to a much higher grade of polish than is necessary for steel. Silicon carbide cushioned abrasive (Micro-Mesh) makes for a decent strop/polishing material, which also reduces the chipping.

I have owned a ceramic knife for over twenty years and when the edge gets `duller` in my opinion I touch it up upon my diamond impregnated wheel. A very fine wheel for grinding tungsten carbide. But allow the wheel to cut into the blade and not out of. Position the knife with the spine sitting upon the rest and allow the wheel tp pass over and through the edge. But keep it cool!! I feel the pressure you are applying to the ceramic edge actually breaks the newly honed extreme edge. I employ only stones upon steel blades to start the edge, then `hone` upon diamond impregnated plates.

Not that oxidation is a problem with tomatoes, but increasing the surface area very much does.

They actually make a "safety" ceramic knifes for cardboard and paper. Instead of a perfectly sharp edge they jave a microscopically rounded over edge. it wont cut skin but it cuts cardboard no problem. The rounded edge also significantly helps prevent the micro chipping. The ceramic utility kife blades last easily a few years in a wearhouse where we cutup a dozen boxes a day.

I was at a friend's barbecue many years ago where I pitched in to help prepare the food. I found all of their knives so dull they were almost useless. I asked if they had any type of knife sharpening tools. Nope. As I was standing there in the kitchen drinking my coffee I looked at the ceramic coffee cup in my hand and got an idea. I finished the coffee in a gulp, rinsed out the cup, turned it over and used the the rough rim around the bottom of the cup like a sharpening stone. In short order I was able to sharpen all of their knives using the cups in their cupboard. Not perfect, but in a pinch...a DIY sharpener.

I picked up a couple of 6" ceramic knives at HF about a year ago for $7.50 each, (a couldn't believe the low price), but this was HF, so try these before buying more. The pointed tip quickly chipped off but the knives still seemed worth the money. I could see a person mistakenly using the blade turned upside down. The handle on one broke off without all that much down force so now there is one knife without a handle. -The biggest problem- HF no longer sells these or lists is the online catalog.

Regarding ingesting ceramic / metal dust, I think no one ought to be worried about this. Normal dust that's in the air and on every surface is composed of lots of things, but in large part it is silica - quartz. Very hard and potentially sharp. And we breathe it and eat it all day long. It's pretty near unavoidable. Is it great to breathe in dust all day? No, but we produce mucus for a reason. How much ceramic dust is getting in your food from using ceramic knives? I'm guessing it's not significant. Thanks for this follow up video, BTW. Really interesting and useful!

I have to say, I have several ceramic knives that are nearly as good as German steel. Of course I have several others that are pure junk (these are the ones I let my wife use). Kyocera tends to be top shelf quality along with kissing crane. I have a black zirconium ceramic that I paid $200 dollars for over 30 years ago and it’s still my go-to blade for fish and other seafood. Cuisinart, on the other hand, is pure junk. You know, the ones I let the wife use, because it just doesn’t matter if she breaks or chips one. They’re fine for veggies and soft food. They aren’t for carrots or cabbage mind you, but most other stuff. I have German and Japanese blades in varying steel types and I use shapton stones for them. I love my steel blades but I don’t think I’ll ever be without some ceramic.
My aunt gave me a ceramic knife and potato peller about twenty years ago. The knife still cuts pretty well but the real star is the potato peeler. Of course, I don't use it that often but it's still sharper than any steel peeler and most of the steel peeler's I've ever used couldn't be taken apart to sharpen (not that I would at $5 a pop anyway) so in this case it's ceramic for the win. I think in a throw away home ceramics are superior because they are typically sharper out of the box and stay that way longer and when knives get dull most households just trow them out and get new ones anyway. In a household where someone is will to sharpen the knives regularly then a good steel knife is better long term.

the flavor transfer is a thing. the problem is most people dont have a good enough palate to taste it. but if you ask a high end chef, especially a chef who uses carbon steel knives, there is a slight taste of sulfur transferred from that. also carbon steel will stain food like onions if you take long pauses between cutting. but i suppose its just the oxidation coming off the surface of the steel, and typically this only happens between the new knife and building a patina stages of carbon steel knives

ב''ה, it has been decades but Kyocera had a wonderfully amazing edge for a not particularly knife nerd out of the box, while some generics had basically the same material but not as shaving-perfect a hone. That said, after maybe 5 years of rough home kitchen usage the "where did those chips go?" does become concerning. If you respect the tool and keep that in mind / don't use a non-cleaver as a cleaver or with metal forks or skewers you can ding into if incautious, worthy investment, and nice if there's some way to recycle scrapped kitchen blades into utility knives. My experience is out of date, so I imagine there's a lot of good manufacturers now and my generics still wow'd for standard cutlery table knife prices, but would figure name brand hopefully still gets you the best edge possible as you probably won't be messing with if you're just cooking at home.

I bought a retractable ceramic blade knife years ago for cutting vinyl shelf paper. I had installed new vinyl as some of them I had put in had begun to tear. It worked great but I was always worried about dropping it and breaking it. A friend moved and I offered to do all her cabinets as she shelf paper in her current house. She bought the rolls of vinyl and it took many hours because she had a LOT of cabinets including built in desks with drawers in the bedrooms and study. Literally every room in the large house has cabinets and/or drawers. The knife never dulled. I still keep it in my kitchen drawer and use it to open boxes, packages or bags and often wondered if I should sharpen it. I do sharpen my steel knives as I have arthritis and don’t have much hand strength. I have gone to friends homes and can’t believe how many dull knives and warped pans people use when I have helped them and struggled to cut or cook anything. The only serrated knife I have is a bread knife which has retained it’s edge since most purchased items are pre sliced or can be sliced by the bakery if asked. Why struggle with something that doesn’t take much time to keep or put an edge on a knife. I sew and used to have an older gentleman drive through the neighborhood and sharpen knives and scissors. He was wonderful at getting my scissors sharpened and properly tightened. I don’t think anyone goes door to door with this anymore and probably why so many people just use dull knives.
Chef for over 3 decades, here. My 2 cents worth, ceramics are okay for the home. In a production kitchen, a ceramic blade is going to break, or shatter. It's not "if" it will be ruined, it's "when". As far as oxidation of fruits and veggies, a somewhat dull steel blade may cause slightly quicker oxidation than a ceramic, but, a properly sharpened plain-edged (non-serrated) steel knife does the best job. For leafy things, like the various lettuces, greens, cabbages, once again, a properly sharp steel blade is good, but, a cheap, plastic "lettuce knife" will do a better job, than anything, and ceramic does a good job. The plastic "lettuce knives" wear out faster than either steel or ceramic, and you can't really sharpen them, but they are, usually, cheap. After all that, my recommendation is, get a good steel knife and learn to properly sharpen, and maintain, it. I'm sure their are plenty of "pros" out there, who would disagree, but that is the nature of Culinary Arts.

Thanks. I now understand why I was able to sharpen that ceramic knife on my Tormek SG-250 wheel. I followed the factory bevel angle which must have been quite obtuse. Some punters laughed at me and said "it's full of chips" but I looked at it very close with a jeweller's loupe and couldn't see any chips. It looked like a regular good sharp edge and it sliced through paper far better than it did before I sharpened it (it was visibly chipped) although I didn't test it with delicate cigarette paper (17gsm). After watching this I now want to run further tests but I don't own one and have to wait for a customer to ask again. Still, great knowledge imparted. Thanks. Great work. Mystery solved.
Another interesting one to try would be Rahvens ceramic knife. They are out of Switzerland. Also, Jende had a good video on getting a ceramic knife to ultra shaving sharp. I still think a good steel knife is better though. Rahven uses their own proprietary flexible ceramic. Just some thoughts, keep up the great work!

Love this video! great job with the comparison and learning that sharpness stops food from turning brown as quick. I learn something new every time I watch your channel! It makes total sense, as a sharp knife will cut much more cleanly through the food and reduce the amount of surface area exposed to the air. A dull knife that tears at the food will certainly cause pieces to stick out, increasing surface area exposed to air. And your sense of humor is awesome, keep up the great work!

Your ceramic knife is decidedly inferior because the handle is just too small and the blade is 30pc thinner so it shatters when dropped. ALDI ceramic knives have far better larger handles and are 30pc THICKER and don't shatter when dropped and the points take many years to chip ( where its thinner) So graduate to ALDI ceramic knives to improve your life. Cant wait for your video on that.
Love my ceramic knife. I used up a bunch before i stopped damaging them. I had to learn to be way more careful. And now I have not changed knife in about 10 years.
Great vid as always. The thing that sticks out in my mind is that the first knives man ever used were made out of stone, which I guess is more silica than ceramic. Either way though, the sharpening is kiiiiind of similar? Those old stone and flint knives were sharpened via chipping. The right kind of chipping gave you a very sharp edge, in some cases an edge that still holds up today (Flint). Hmmm, actually it's more like chipping was used for sharpness in the old stone knives, but has the opposite effect here. Ugh, never mind, move along.
Bought one, but never again. Used it to separate two frozen hamburg patties and only after I ate the burger I noticed microchips in the blade, dozens of small triangular voids. Meaning I swallowed these micro chips and there passing through my digestive system. These damn things should be outlawed. Lucky me they passed through without slicing my intestines open. These blades shatter way to easily and should be avoided for food products. Some of the chips where 1/32 of an inch in size. I thought I was chewing on the infamous bone fragments too often found in hamburg.

I bought a ceramic knife years ago at the dollar store after seeing the "blixa bargeld makes risotto" video and it's still sharp and works great for me. However, the tip has broken off and the white blade has become quite stained. Great video!
I bought on after hearing the hype. The blade chipped in lees than a week. Still used it. It was sharp, but chipped again. Within 2 months my new, very $$$ looked more like a bandsaw blade. Never again.
I feel bad for freehanding my ceramic farberware successfully and mentioning it about 4 years ago 🤣 still own that knife and still own the same two red and green DMT "stones"/plates. Makes me want to dig them out and play around again. I believe I may have added serrations towards the handle to make it an even better salt water knife after making it a new handle.
Buying a set of ceramic knives was on of the best decisions I've ever made. I use them only for cooking. Years and years have passed and they are still exactly the same as when I bought them.
thanks for the update and further information. i still like Ceramic in my Kitchen uses, for the light duty purposes for that zero maintenance angle. anything that's heavier duty i still use Steel since yeah you start to cringe at using it on tougher stuff, afraid that it's going to snap or chip. so Cutting Fruits&Veg, Cheese, softer types of Meats, all that general purpose stuff, the zero maintenance is nice. :) oh and especially for a Bread Knife or anything Serrated? since sharpening those is a PITA and nobody wants to do that at home. so i use Ceramic for that since nobody is going to bother sharpening that stuff.
You are totally right that the majority of people do not have sharp knives at home and have likely never thought about sharpening. Most don’t know how to use knives well either. I am no chef outside of what I cook for myself but watching other people try and cut food is just painful, something that with minimal technique would take 10-20 seconds I have seen take up to 5 minutes for some people. People just don’t know how to handle knives, they are slow, inefficient and treat them like they are dangerous and then go and do stupid stuff. Just like any other tool the only thing dangerous about a knife is the person. Learn how to actually control what your hands are doing and be careful and you will be fine with even very sharp knives. People that do think about sharpening often aren’t much better, especially if they just buy a cheap sharpening tool (like the ones that you pull the knife through) or one of those sticks they see professional chefs using. Now both of those types of tools if done well are fine for sharpening but in a home kitchen they just aren’t. I have seen pull through sharpeners that didn’t actually sharpen the knife, it just put micro serrations on it and made it harder to properly sharpen. All most knives need is a few minutes on a stone every so often, maybe a little longer if it has been left a while or been abused. The only knives that consistently take me longer are a couple of old dark Sabatier knives, definitely not stainless, rusts very quick (leave it wet at all even just for half an hour and there will be some rust) and the knife other than the edge is dull and dark rather than shiny. The knives take a while to sharpen but they stay sharp for a long time too and I seem to be able to get them sharper, great knives just not stainless. I have no idea what kind of steel it is.
Rahven flexible ceramic knives are a game changer. I bought one when they first came out and it has been in daily use since and is still roughly as sharp as when I bought it. I believe the proper term is elastic ceramic and you can flex the blade and any normal drop is not going to damage it.
It's so funny to me seeing the Kyocera knife when my first phone was Kyocera. I haven't seen them anywhere else. Just knives and phones.
This was a comprehensive "how to" on the use, care, and maintenance of a ceramic knife. Glad it was you who invested all this time😂 Thanks! Would it be a good idea, in most cases, just to keep buying new ceramic knives instead of sharpening them?
I threw away my ceramic knives when I noticed the edges were chipping. I don't want anyone to be eating chips of ceramic.
Thank you for this video. While I don't own a ceramic knife, I was buying into the hype and was seriously going to buy some ceramics for my kitchen. After this deep dive, I've come to the conclusion, that I am too rough on my knives to have ceramic in my kitchen.
I would like to see how the factory sharpens ceramics in production. And for reference S30v is rated slightly higher in edge retention than m4, not to mention Rex 45 and Rex 121. Those steels get very hard and tend to be be chippy like ceramics at the equilent angles. At any rate, very good demonstration and explanation for those not reherced in the the field. Well done and thanks for sharing!
Just happened upon your video and I must say, it was surprisingly entertaining and informative. And although I hate little video inserts, yours were well done and quite humorous. Keep up the good work!
My dad was a 3rd generation master shear and knife craftsman from Solingen Germany, where Wushöf are made. I was lucky enough to be taught the ins and outs of blades (oh god pun not intended). He sharpened knives perfectly. He actually helped their business partners in Japan develop a ceramic hair cutting scissor! So he also worked with ceramics, so he knew what you discovered here. He told me almost the exact same knowledge! It’s the grain by the way. Ceramic doesn’t have grain, steel does. It’s the microscopic structure of this grain that allows you to sharpen it to a hair whittling edge. Ceramic will hold longer but it’s far more brittle and if you try to get it to the same sharpness of your steel it will chip. Grain and grain direction is incredibly important when making steel knives. And though I’m eternally grateful to pops, God rest his soul, I now walk this earth with the curse of watching how almost every single person mistreats their blades, and thinks knives are consumable and have to be replaced. A good blade with proper care will last you a lifetime. Thank you for sharing this knowledge. Everyone, you will spend far more money on cheap knives and scissors in your life than if you just save up for a good knife. Unless it’s completely destroyed somehow, you will have it forever. If you don’t want to learn how to sharpen yourself, take it to be sharpened by a professional. It isn’t too expensive. Even with routine sharpening you’ll still be paying less than continually buying crappy knives. And DONT PUT YOUR KNIVES IN THE SINK, FOR THE LOVE OF GOD

I like how up close the ceramic blade looks like ice. Also, I work at Walmart stocking and with a normal razor blade I'd change it out after like 3 months. The actual razor blade itself though gets dull after a few weeks, slicing through stuff packaged in think plastic or cutting through shrink wrap will show that. I just usually use more force but eventually I need a new one. Then I got a ceramic box cutter and that ceramic blade has lasted me two years before it broke (when I was being careless, it would have lasted longer). It was amazing just how long it stayed sharp when used properly and with a good application.
I have exact this knife for like 15 years? Still my favourite for cutting vegetables, fruits or soft meat. Still very sharp!
Smart and dry-humor...a winning combo in making a good video about a "dull" subject matter. Did anyone notice a sharp pun in this comment???
Yes, yes, steel knives are really good, if you sharpen them regularly and good at sharpening them, but most people are not. Most "off the shelf" knife sharpeners are basically useless junk, so many household can't ever sharpen their knives to even the same level as new ones (let alone a shaving edge). Ceramic knives are for them. They remain usable basically for infinity (even if they lose some of their initial sharpness), if you take care of them. And that's all your average joe really needs.
NIce, I'm running to the Dollar store immediately to get one of these cheap ceramic knifes. We now use Stanley (and other brand) utility blades to cut cardboard boxes to size for re-use or to put them in our recycling container but we all know that a dulling blade takes more force and that results in increased chance for accidents. Even the original Stanley blades wear out within one busy day so if I get more use out of a cheap ceramic knife and if that increases safety then that is surely worth it - even if I cannot sharpen the blade and use those knifes as a disposable one.
I've used good knives for cooking in steel for many years, and I have a few ceramics as well. For baseline cutting sharpness, the ceramics have amazing wear. For fine cutting, an ice hardened blade with a 34 degree compound angle works as well as I've seen, but requires regular sharpening.
If you're looking for a cheaper way to sharpen your ceramic knives, plain old black (silicon carbide) sandpaper also works.
Ceramic knives are awesome! I've had the same knife (Kyocera 4.5in) as you since it came out, more than 15 years ago. Pretty sure it was $35 dollars then as well, lol. But the fact of the fruit turning dark isn't about stainless steel knives, it's about carbon steel knives! Carbon steel leaves a taste behind on fruit and veggies and will turn an apple dark because of the composition of the blade. My dad used Old Hickory brand knives religiously until they wore slap out. After I cut an apple up with the ceramic knife he asked if I was going to get a bigger one! Which I did later for the tune of about $159. I also have stainless steel knives because I was always afraid of dropping the ceramic and it shattering (which has never happened).
browning lettuce is my only biased application with ceramic knives. and it is very real. I have been working as a chef for years. my romaine and iceberg only get the iceberg. your opinion would be worthy if you had the same level of experience. and no self-respecting cook uses his knives for cardboard.
After cutting a lot of glass, tile, my friend has found using antifreeze as for cooling and lubricating it reduces the chipping a lot. You may want to give that a try. I could take the credit for it. All goes to my friend Tom.
Great video, but wrong about the diamond stone... I used 400 to 1000 grit diamond sharpener from Lidl at £10... plus wet sandpaper from 1500 to 5000 grit. Granted,it takes a bit of time but not money 😊. I was looking for ceramic knives sharpening for years, so still happy you posted this
I never thought of sharpening my ceramic knife with a flat lap machine before, now i think I'll have to try it out.
I can't express this enough that I like your video very much, and always learned something from it. :D
I owned one ceramic knife, it was also a Kyocera. I didn't like the idea that all of the small chips off the blade ultimately were eaten by me and my family. Fun fact, I bought it in Spain just before visiting a museum, where our bags had to go through an airport style metal detector. The knife (still in it's packaging) was not detected.
Thanks for the video - it was very informative! A couple of observations (I'm not an expert but these worth looking into): although metals might not play much role in oxidation of the food, amino-acids and other compounds in the food might react to metal in the knives. This is less of a case for stainless steel knives, but nevertheless there's a very slight influence on a taste. Although majority of us will never tell the difference. Second point is about chips in the food: our digestive tract is has a very agressive conditions inside. If microscopic metal chips are introduced, I assume, those chips get dissolved or at least covered in salts, as a result of chemical reactions. Whereas ceramic is almost inert and doesn't react with anything in our body. Although, from what I read, if the chips are not visible (i.e. small enough) they can pass through the digestive system without causing harm.
Spectacular finding. I think this understanding will also help me select an appropriate apex angle on steel knives which also chip somewhat during use when the angle is quite acute. Thank you!
If you live in CA, Kryocera has free sharpening service. But if you are on the East coast, then the shipping cost is about the same as buying a new one.
Lots of comments about tungsten carbide but leaving out that we don't sharpen it to anywhere near the same included angle as a knife. TC/CBD tooling doesn't cut like HSS but tears mat'l vs pierce it. Up sharp is a matter of the grit used to sharpen. btw, for the toughest materials we use ceramic inserts. They rip like TC inserts and similarly aren't resharpened.
I had to cut a galvanized fence post with a battery sawzall , battery died with about 1/4 cutting left. Grabbed a " ginsu" style steak knife I found on the job years before, it was so sharp, cut like a new hacksaw blade.
The moment "It feels like chips" and then your finger touching chips killed me 🤣🤣🤣
Would you please do a video on how you sharpen a straight razor for shaving? You're the only one I trust anymore to show the correct ways of sharpening.
I do cut enormous amounts of cardboard, so this was immensely helpful and interesting!
I think what's wierder is the manufacturer, Kyocera, known for making excellent ceramic and carbide tooling also makes copy machines.

Several years ago now, I made a ceramic and carbon fiber laminate straight razor. It was deeply terrifying to shave with, but shaving with it was entirely doable. Part of the trick for a more durable edge is indeed to take the edge up to a much higher grade of polish than is necessary for steel. Silicon carbide cushioned abrasive (Micro-Mesh) makes for a decent strop/polishing material, which also reduces the chipping.
I've been trying to figure this out for years. It never occurred to me to change the edge angle. Thanks 😊
amazing. i got some dulled ceramics. now i know what to do..... sharpen my steelies.
Is it just a coincidence that this video popped up for me and I purchased a knife sharpening kit from FB marketplace earlier today? Probably because I googled the brand of sharpening kit.
Ceramics in the kitchen are perfect for any normal person.. Sharp enough to cut just about anything w/out needing me to go in the garage and sharpen it... lol that's their purpose. 3 kids and a wife who definitely does not care about knife sharpening and it'll make sense. Thx for the vid
I have owned a ceramic knife for over twenty years and when the edge gets `duller` in my opinion I touch it up upon my diamond impregnated wheel. A very fine wheel for grinding tungsten carbide. But allow the wheel to cut into the blade and not out of. Position the knife with the spine sitting upon the rest and allow the wheel tp pass over and through the edge. But keep it cool!! I feel the pressure you are applying to the ceramic edge actually breaks the newly honed extreme edge. I employ only stones upon steel blades to start the edge, then `hone` upon diamond impregnated plates.
10:45 as a chef for over two decades, I see clear difference; the iron blade does need some pressure like the ceramic, but then cuts a bit sooner and way cleaner. The ceramic knive wrinckles the tomato skin, while the iron blade, once it's through, cuts clean all the way down. Not that oxidation is a problem with tomatoes, but increasing the surface area very much does.
i never thought a video about something as simple as knives would be so interesting, ill prob stick with steel but this was really cool
Use a paper wheel with diamond paste. Heat is a non issue with ceramic. Can get sharp fast with paper wheel or power equipment!

Should watch my last video 😉 its linked in the description 👍
Your videos helped me improve my sharpening. My knives are way sharper than before. What helped me was the technique used to sharpen, and the need for a leather strop. Thanks to you. (I did buy the jewelers loupe but couldn't see much. I saw a little of burr, but I think the majority was good).
