NIce demonstration, now I know I won't be having any single bewels to home :D Definitely need master grade sharpening skills to get the job done.

Just watched uraoshi video, and it quite clearly answered my question however, I do have another question. So as I have seen, the general process seems to be sharpen higher on the major bevel, lower on the major bevel, uraoshi, then burr removal. Since you emphasized that uraoshi can easily be over done, would you recommend that uraoshi is done every time one sharpens their blade? Of course, I know this can be a highly subjective question, but just wondering.

Really solid video 💪💪👍👍

Legend! Thankyou!

Oh right, the site where I bought it were actually selling it as a single bevel.well thanks for the advice, I'll have another go at it tomorrow. I think I'll practice my sharpening skills on that knife before I invest in a better one. Thanks again for your advice and the videos.

you took off the sharpie with a medium grit stone, do you usually do this and the other steps just once or more times?

Hello Very good video. But I have a question on single bevel sharpening. Have bought some really inexpensive (15 $) yanagiba in order to train on single bevel sharpening. But even if I try to follow your video I do not manage to got it arm hair cutting sharp. It seem like that I am not able to get rid of the burr on the flat back side. Do you think that the steel is to cheap in order to get it sharp, or do I have to practice more? I can get a cheap double bevel knife razor sharp with no problem.

very few of those are actually knife craftsmen... and if you're looking for a traditional knife, i would say take a look at our gesshin hide line... its my personal favorite.

Any additional advice for restoring a polished out shinogi? Hissatsu blade? Thanks. I pretty much polished out the shinogi and the yokote. Oops

I've a question about the uraoshi. Is it normal to have knives with an uneven shaped uraoshi? I have a knife with a strange uraoshi where the tip uraoshi (front 2 cm) is thicker than the rest of the blade, so it looks more like a bottleneck than a gentle Λ. I don't have this experience with my old company Aritsugu or my Sakai Takayuki (therefore I don't think it's a technique problem), so I've been wondering is it an imperfection on the part of the knife maker?

the simple answer is the highest girt you have, but sometimes that can be too high. You want it to be a finishing stone for sure, but aside from that, edge preference can have a lot of impact on what you choose to do. Ideally, harder stones will work better for microbevels than softer ones. And, also remember that micorbevels are not necessary 100% of the time. They can be very helpful in specific cases, but overuse seems to be a common problem nowadays. Fee free to bug me with any followup questions.

Blade flat and parallel to the stone during uraoshi?

Hello John. first of all, Great videos! love your channel. By the way, I am having few troubles with sharpening ura. I found it is impossible to remove burr of ura when ura is flat on the stone.I spent like 3 mins to remove burr of ura, but nothing changed. But when I give slight angle (like 5 to 10 degree), burr is cleanly removed. I am using cheap tojiro yanagiba (around 30 dollars) and some people state that if you sharpen cheap and soft stainless steel yanagiba, you need to give between 5 to 10 degree angle for uraoshi sharpening. Is that true or did i just ruin my knife? Thanks a lot!

Hi, thanks for doing these videos. They helped me a lot with sharpening my knife with a stone for the first time. The only trouble I had was the bevel on my knife is very small so it's hard to see the angles on it, have you got any tips that could help me cope with this? Thanks again.

yokote requires great pressure control and angle control... the tip adjustment is different. The tip sharpening is separated into two parts at different angles of approach. There's no easy way to do it... just practice.

Hello Jon, The quality of all of your videos are extraordinary! I do have a question about the hamaguri edge. When you did the top bevel (Shinogi line down to the lamination line) I was surprised to see sharpie was removed from the lower bevel (lamination line down to the edge). Because the hamaguri is a compound bevel, shouldn’t the sharpie only be removed from one side of the lamination line at a time? Obviously the sharpie says otherwise, but I don’t understand what is happening.

Sure... knife grinds arent always perfect, so you will see some variation. This was a yanagiba that i ground as part of my training in Japan, and clearly my grinding was not the best. You will almost always see some inconsistencies in terms of the grind. In an ideal and perfect world, you would be correct though. I just dont often see ideal situations.

There are some synthetic stones that do a really excellent job with that kind of contrast though... for example, we have a jinzo aoto that is designed to leave that kind of nice contrast. There are others as well. Not all natural stones will do well for contrast, but there are many that can. But with natural stones, technique (in terms of pressure and water control) come in to play much more. Have you considered using uchigumori finger stones? That might be the easiest way for you to consistently get nice, smooth looking finishes with good contrast. Not the least expensive way, but they work well.

Not sure if you will see this but I am having issues with the tiniest of chips in my Deba after cutting multiple fish. They are mostly towards the heel as that is where I am contacting bone but I’ve never run into these micro chips as I am with this new Deba. It’s White #2 steel and a nice knife it’s 7.5mm thick above the heel in the spine so it’s very heavy and proficient at running through fish bones but these darned tiny tiny chips are killing me. Any advice? I’m not a big fan of microbevels across an edge but I’m thinking about putting a steep microbevel just in the first 2 inches of the edge. Thanks!

I know you're not a big fan of microbevels, but they really do help. You dont need to do a lot of them to have them be effective. For example, if they are so pronounced that they take a crazy amount of time to remove in the next sharpening, they were probably too big. In terms of angles, in the 35-40 degree range for a very light stroke or two should do it. If you wanted to do it only near the heel, there are no rules against it :) Some japanese chefs also do a microbevel on the back (ura) near the heel (the last 1-1.5in or so on a 180mm deba for example) and use that for really rough work (i.e. splitting heads). That is an option too, but I really dont like that, and once you do it, going back is really not easy.

If you're looking to have it look nice/new again, there are a number of ways to do that, varying in cost and ease of application (for lack of a better way of putting it). However, it is important to make sure you sharpen from the shinogi line down, as a function of maintaining a useful cross-sectional geometry that cuts well. Kasumi Finish... necessary, no. Looks great, yes. Bug me if you have any questions about sharpening or kasumi finishes.

@BackBurnerKitchen

6 жыл бұрын

Thank you! So you sharpen pretty much only until the you remove all of the blue sharpie from your blade. I am guessing this is only to show the whole area that must be sharpened and not how long you should sharpen the knife or is that long enough on the bevel beneath the shinogi line? and then you continue to sharpen the edge bevel until you raise a burr. Also if you are using a larger progression of stones would you repeat that for every stone or just continue on the edge bevel and the back of the knive as you progress?

@JKnifeImports

6 жыл бұрын

The sharpie is just used as a guide to help assist in angle accuracy. The length of time required is dependent on other things. For example, the shinogi line should move up the same amount that the edge will move up. The edge moving up will depend on edge condition (are there chips, etc.) and how small of a burr you can consistently feel. You would ideally use your full stone progression from the shinogi-line down, but that may not be true 100% of the time. I can think of at least a few exceptions, though, they are exceptions rather than the norm.

@BackBurnerKitchen

6 жыл бұрын

Ok! I understand. Next question. When I sharpen double edge knives, I raise a burr with the first stone, remove the burr and then continue with edge trailing strokes to refine the edge through a progression of stones. Is that the same idea here or do I continue to raise a burr and remove it through the progression?

@JKnifeImports

6 жыл бұрын

Even with double bevel knives, there is some burr formation that happens at each grit until you begin the burr removal process. The goal is to help reduce the size of the burr at each stage until the final step of burr removal. Does that make sense?

what do you mean by that?

the sharpie can be reapplied before each stone if you find it more helpful (it often is a good idea as you get started)... for normal sharpening, i usually use a coarse, medium, and fine stone (sometimes more than 1 fine stone). Outside of uraoshi and microbevels which are only done on a finishing stone, the rest of the sharpening process should be done on each stone.

removing sharpie is just part of it... you should also be looking for burr development when sharpening the edge, even raising of the shinogi line when sharpening that area, making sure both move at the same rate, checking to make sure you have a nice even scratch pattern along the blade and that the scratch pattern reflects the kind of stone and grit level you are using. What specifically is wrong with yours right now? Not sharp? Doesnt look nice? Both?

When sharpening a wide bevel, but double bevel knife, would that require the same process highlighted here, just without the uraoshi sharpening? I'm uncertain if I would use a high angle microbevel like in this process with that kind of knife and just treat the lamination line to the edge as the main cutting edge and develop a burr there, or if I would just grind down the wide bevels a bit like the first part of this process focusing pressure near the shinogi line and then do the usual 9-15 degrees or so as you do on most double bevel knives after that little bit of thinning. Instinct would tell me that a double bevel knife isn't designed to hold an edge that would require an angle so low as to hit the lamination line to the edge, and that just thinning using the wide bevel laid flat as a guide to maintain the original geometry and then putting on the usual double bevel 9-15 degree would make sense, but I'm really not certain of that.

After I thinned the knife, and then formed my bur doing the bevel "compound" like you suggest, I then turned the knife over to do some back side sharpening. I did just a few quick light strokes on my 6k stone like you showed here, but just that alone was enough to raise a burr on the bevel side.... so I then did some stropping strokes on the bevel side and AGAIN I got a burr on the back... so I did the back side again and ANOTHER BURR! I am using light pressure and only on the forward stroke. What am I doing wrong here? I've never had a Japanese knife with white steel hold a burr like this... they usually come off right away considering how hard and brittle the steel is. I am trying to do this WITHOUT a micro bevel.

I use a 1000 grit and a 5000 grit stone from naniwa. Greetings from Holland, Thijs Toetenel

Vierentwintig Karaat you probably want to start off with a coarser stone on the front side and a medium girt stone on the back for the initial work. Once everything looks good, switch to a finishing stone for the back and a medium grit stone for the front. The a finishing stone for both the front and back. As long as you form an even and consistent burr from heel to tip and then remove it, your knife will be sharp.

I also have a 400 grit stone. So i Should use that for the front? And do you suggestie getting a finishing stone With a higher grit like 10.000?

Vierentwintig Karaat Yes... i think it will help speed up the process of cleaning up the high and low spots and form the burr more quickly. Just be careful to not overdo it, and make sure you are being angle consistent. With the higher grit stones, its not necessary. Some people like to go that high, but most do not. 6-8k is about perfect for most.

Could you what the first and second stones are. for the second, it sounded like you said "Manzanto" but I probably missed that :D. thanks for these excellent videos

Yeah... we have people send in knives for thinning and sharpening all of the time... feel free to e-mail me with questions if you have any Jon@JapaneseKnifeImports.com

Great video John, you are the best, but quite frankly I think I will stay away from single bevel knives because the sharpening seems very much more complex than double bevel.

Its a little bit more complicated, but in reality its not that hard. Anyways, if you change your mind, know that we are always here to be a resource for you along the way.

Essentially both.

I know im quiet late😅 anyways, what grid is the first stone?

What stone are you working on? Lease tell me

i shot this a long time ago, so i'm working just from what i can see in the video. The first stone appears to be a gesshin 2000 grit stone. The second one is either a gesshin 4000 or 8000. The third is a natural monzento. And the fourth is a shobu suita.

natural stones dont really operate in the same way as synthetic stones with regard to grit ratings... lets just say its pretty high grit finishing stone (its my shobudani renge suita)

are you 100% sure the back is flat? Honestly, i would have to see the knife to figure out the best way to sharpen it. If you want to shoot me an e-mail with some pictures, i think i should be able to help. You can find my e-mail address on our website JapaneseKnifeImports.

So the two "styles" of sharpening a yanagiba that i've found here on the youtube is either your style where you focus on the shinogi line first than the edge creating a small arcing bevel between the two and the other style is a more simple style where they dont bother with that step and just does a straight bevel between the shinogi and the edge, The uraoshi is done the same way in both styles. As im having a really difficult time finding that shinogi angle im scared that i will undercut the angle and fuck the knife up is the second style of sharpening worse in any way?

they are different for sure, and both have their strengths and weaknesses. The second method you're describing is called "beta-togi"... "beta" (pronounced like the "be" in "best" and "ta" in "talk") is onomatopoeia for the sound of laying something down flat on something else.... consists of laying the bevel flat on the stone entirely. This kind of bevel will feel a bit sharper, and requires a bit less technical know-how to be able to do effectively, but the edge is much more brittle, food release is not quite as good, and the shinogi line and edge geometry are linked. Hamaguri edges, like what I teach, will not feel quite as sharp (but still will feel extremely sharp... we're talking small differences here), but will be more tough and durable, will have a longer lasting edge, better food release, and allows for independent control of the shinogi line and edge, which can be very helpful. Neither is wrong. Almost every craftsman I've ever met in Japan recommends hamaguri edges (I honestly can't think of one who didn't recommend it, but I don't want to say 100% just in case I forgot someone), but they also understand that some people feel more comfortable with beta-togi. Most chefs who have not had any professional sharpening training will use beta-togi. This is often for no other reason than just not knowing about hamaguri, though I've got a few friends who enjoy the feeling of the edge from beta-togi a bit more, and are capable enough to not have chipping issues with this style of sharpening (as the edge will be more brittle). Does that make sense?

Wow thanks for the thorough answer. If you dont mind, i just recently (2h ago) tried to sharpen my yanagiba the way you showed in the video, the blade got sharper than it was out of the box, however i kinda butchered the finish and the look of the knife. (please dont take this as if im blaming you) If you dont mind, could you maybe take a moment and look at some picture i took of the result and maybe give me some advice on how to turn the knife back to something beautiful again? The stones i use where the only one i have a shapton pro 2000 and a shapton pro 8000. Pictures; imgur.com/a/hNPxLDz Thanks in advance

looks like you didnt spend enough time to remove the previous scratches (from the finish of the new and unsharpened knife) before moving on.... a lot of those splotches are from the original kasumi finish. A bit more time should clean that up. I often use a coarse stone for this, as its faster. But if you arent comfortable with sharpening quite yet, the medium grit range will be ok... it will take a bit longer, but thats ok. Also, the shapton stones won't leave contrast between the 2 steels, but that is ok.

realistically, you dont have to remove any more metal, if you're ok with the way the knife looks. There's nothing wrong with it functionally, and the scratches will come out over time, so no need to rush. If the look bothers you enough, then feel free. Also, i noticed some scratching above the shinogi line, so be careful about rotating over the shinogi line a bit more when you sharpen next.

What was that really muddy stone?

I am asking as an experienced specialist at what angle to sharpen single- and double-sided Japanese knives because I have such knives.

@JKnifeImports

6 ай бұрын

single bevel knives essentially have the angle built into the wide bevel, so try to follow that as a guide. Double bevel knives are far more flexible. Generally, angles from 10-15 degrees per side are a safe bet range. The higher you go (i.e. closer to 15 or even beyond that) the more durable the knife will be but the less sharp it will feel. The lower you are (i.e. closer to 10 or even lower), the sharper it will feel, but the more brittle it will be.

do I need the mud stone? Was unclear - I just have 1k and 6k

ideally, you want to employ edge trailing pressure on the bevel size and edge leading pressure on the ura (back side)
