As a trained silversmith I have to give you a solid 90-95% “Thumbs up” for your creativity in this video! The only reason why I can’t give you the full 100% is that you overlooked a _really_ crucial detail that newbies at this would miss, and that is that there needs to be a cold water bath by the buffer (big enough to hold the entire blade), and that the blade needs to be quenched each time it starts to warm up - long before it changes color - to prevent the person honing the knife from destroying the heat treatment (tempering) that allows the blade to maintain its Rockwell hardness and hold an edge. About 20 years ago, while still in school, I made that mistake with a tempered steel onglette type graver point that so quickly changed after accidental bluing that it went from feeling like a knife through butter to something more like a bulldozer through rocky soil, when working on copper sheeting - a lesson I’ve never forgotten. This obviously wouldn’t be an issue with a $12 Mora, but on a pricier or custom made blade, that could be a very different story! (Just my $0.02 worth...)

I'm really pleased with this! It works like a charm kzread.infoUgkxDcr-y2Pf6xdnrFHrSP7dl9kpKaCozcSQ Takes less time than my old electric sharpener because it can take more off the knife faster, and then it smooths out nicely with the finer grit polisher. I don't know how long it will last before the grit wears away, but I wouldn't mind having to replace it every once in a while.

This is something I'm going to have to try! A word for anyone considering this method: always use the lightest touch when honing with that wheel. Solid plywood spinning fast like that will heat a blade *very* rapidly if too much pressure is applied, potentially ruining the heat treatment at the edge of the blade.

I just made an 8 inch wheel from some high grade finished plywood. I followed the steps and tried various types of polishing rouge at 20 degrees. I did a couple of knives and looked at the edge under the microscope. Clearly, each bevel is free from defects and is quite smooth, uniform and polished in appearance (nice! ) (very unlike using a steel) . However the edge point itself was not perfect and needed a bit of touch up with a leather strap. Result=good.

I tried this and bought a bench grinder specifically for this application which I set up in the pantry. Works great, I use it everyday. Thank you!

Tips for those trying it: Get two type of compound. One fine (white from link in video description) and one ultra fine (green from same link). Put the fine on the wheel and take your time so the blade doesn't get hot or use an oil or water bath occasionally to cool the blade down between passes. Put the ultra fine on a nice leather strop and use that to finish the polish and perfect the edge (if more than a great working edge actually matters to you).

I sharpened a lot of stuff by hand over the years. The most time I spent was sharpening an 18" machete to razor-sharp starting from a hand file then going to a cheap 2 stage whetstone. It probably took like 5-10 hrs. In the end, it was sharp enough to shave with and could cut through a 2" tree in one swing. I would say this is a good method to get similar results in a lot less time.

I had a grinder with one side available so I immediately went into the shop and rounded up the materials and built one and it works beautifully. On one side of my grinder is a buffing wheel which I used for polishing knives that I build so I already had the jewelers rouge (grinding compound). Don't listen to the people who always try to convince themselves that they are smarter by belittling the accomplishments of others because they usually have none of their own. Use a little common sense and a light touch and there are no chance of overheating the blade. Thanks for the post. I always love a good idea and this one was a keeper.

Ooooh this looks great. I have all the stuff and so many knives needing sharpening.

I found this about 3 months ago, and built my wooden sharpening disk. It works great. All of our knives in the house now are razor sharp. I can shave with them. I also built a 8" inch by 1 inch leather stropping wheel by glueing layers of leather together and cutting it into a disk and shaping it using a chisel. This now gives me a two stage approach and enables me to do light maintenance on my knifes with less metal removed. Thanks for sharing this video. Knife sharpening is now therapeutic and satisfying.

Always looking for other options in trying to improve my knife sharpening skills. Great video. You put some time and thought into this rather than most poor videos of guys who turn the camera on and just wing it. Many thanks for your efforts.

I used this method years ago and it actually dulled my knife, but I fixed up the wheel and added the compound and tried again, it saw barely any progress but I kept going for another 15 minutes and it actually got pretty close to razor sharp, I found the problem which was the compound I was using was for leather and not that abrasive. Not to mention the blade's steel was a hard steel, so I bought the same brand of polishing compound and it worked. Cuts like butter. Hopefully some one you found this helpful if you were having trouble

@koviack Well the broken parts will fly around at high speed.^^ So you should use a decent birch plywood, remove material to balance the wheel and use very little pressure. It's also important to use the same diameter as the machine wheels so you won't introduce highly different forces that the grinder wasn't supposed to withstand.

@koviack Eye protection is recommended, obviously. Grind wheels can/do shatter (esp. in angle grinders) but I can't imagine a thick plywood wheel would disintegrate at this size/RPM.

I'll stick with the OP's dimensions anyway as he proved they work fine over a long time frame, so there is no need to alter them.

I mounted a hand drill on a vice and used an MDF disk with it. Even at medium speed the wheel worked great. Even a small bit of compound lasts a long time. A steady hand and a light touch works best. I agree with safety concerns though. Always position your self and hands so that if your knife or whatever you are sharpening slips, your tool and hands move away from the spinning disk. Haven't tried it with plywood yet but I will give it a try soon.

I love sharpening knives. Thank you sir for your informative video....

This is groundbreakingly awesome. Great video!

Excellent beyond excellent video! Very eye opening and I'm so excited to give it a shot!

The only problem I've had with polishing edges of knives, is that the sharpness quickly wears away. I prefer a rough edge like a scalpel blade. The most important aspect is to get a good edge that can be deburred many times before a new edge needs to be created. For old school barber blade shaving, there's stropping. Of which, the method in the video is a more mechanical way of stropping. For pocket knives or kitchen knives you want a rougher edge that can grab the material that's being cut.

Only thing I can add, WEAR EYE PROTECTION. Especially when you are sure you dont need it.

Interesting idea. I use a small belt sander so I can go anywhere from 80grit to 2000 grit to stropping and compounds. This is a great idea though. Wood is easier to come by than sandpaper. Great video, thanks for making it!

This is a fantastic idea. I do believe I am going to get some leather and put in the wheel, then add the polishing compound to that. A spinning strop. Thank you so much for sharing this!!!

Really interesting! Well done, TAOW, and keep up the good work 👍🏼

Nice one, thank you!

Great idea on the cheap gonna have to put this to use thanks

I so glad you mentioned the rotation of the wheel because the first thing that came to mind was the people that are going to die from trying this but do it wrong.

You can also turn a belt sander upside down(it helps if it has a locking trigger) and start with some fine grit sandpaper. Set it up the same way as the video ,so the belt is spinning away from you and sharpen the edge the same way. The way the belt goes around a roller can give chisels and knives a nice hollow grind.

I'd just like to point out, with this method, you're basically creating a big burr (By sharpening from the spine to the edge). This big burr will mean that you can get your knife really sharp, but the edge will be dulled incredibly fast (it will require honing very very often). Many knifes just need honing or stropping to get sharp (replacing the bent burr into place). The longer the burr, the faster it will bend, this is why knifemakers sharpen from the edge to the spine. I'm not saying this is a wrong thing to do, I just want to provide more information as tho who this technique is for. A knifemaker would not use this (unless they don't know what they are doing) and this will require frequent honing and sharpening to maintain the edge (far more frequent than one would normally). If you don't know how to sharpen and don't want to learn, then this is for you. -Knifemaker and blacksmith.

@Taunus-Tim

7 жыл бұрын

Karl Hurtubise wow. Imho this is nonsense. I don't know on which planet knifemaker sharpen from edge to spine, but not at the one i live. The burr won't get to long or even stay there forever, it will eventually rip of and break off of the edge, at least after cutting two or three times into some wood f.e. This happens on a microscopic level. You can easily watch this with a cheap USB microscope. There is absolutely no advantage by grinding from edge to spine. It's more the other way around! When you sharpen in the direction of the spine, small steel particles get pulled towards the spine, ripping small teeth into your edge, which make the edge rough. When steel is soft, a burr can get pulled under your edge, folding around it. Watch Japanese chefs or traditional Japanese smiths how they sharpen knifes or swords. They do it from spine to the edge. And they do this for some longer time than any american. Your method has its truth when we talk about very rough grinding with low grit numbers, where the burr is still thick enough to hold on and bend. But when you grind with 3000 grit or more, the burr gets so incredibly thin, that it breakes or rippes of. Though this works only for hardened steel.

@Taunus-Tim

7 жыл бұрын

Karl Hurtubise i forgot one important point. When you grind a knife on a whetstone, you absolutely need that burr. Only with the burr you cam actually feel if you grinded long enough on one side of the knife, because it will only be feelable if you your grinded surface of the right angle reaches the tip of the edge. When you feel the burr you change sides, then use a lower grit and repeat until you feel that burr again. If you reached the finest wanted grid you can break the burr by grinding one stroke from edge to spine or you use a fine steel sharpener or a leather belt. The problem you mentioned really just occurs on a macroscopic, rough level, but not on a microscopic level on very fine abrasives.

by grinding or sharpening from spine to edge, you still create a burr, it is however a lot smaller. Japanese knife makers also sharpen from spine to edge on whetstones,they actually do a back and forth motion to discard any burr more efficiently. so I don't know at all where you get your info from. Also, on a microscopic level, you always have a serration pattern, as it is exactly that that provides a cutting edge. Without serrations (although the finer they get, the better) you would only be able to cut with pressure, not with back and forth strokes. Those serrations are essential and the finer and more regular they are, the better the edge (other factors as angle and geometry also play a factor) Usually, sharpening is done by pushing the edge in the stone, and then final stropping of the knife is done by drawing the edge on a strop. Now your point about the ripping of small teeth into the edge is just exactly what grinding it does. With a 3000 grit stone, those channels are extremely tiny and will create the serrations needed. Whether it is steel particles or stone particles that create these channels, they will be the same size also. They are still created by sharpening from spine to edge anyway and those channels will be exactly equal, the only difference being the burr size (by pushing the edge into the stone, the burr is created from the very fine edge being pushed up with pression. Stropping (or honing ) is then needed in both methods to align the burr. The longer burr will bend more quickly and need re-stropping faster, it will also tend to chip off. A very simple search on google will provide info in concordance with my view, and blacksmithing/knifemaking manuals also provide more info. Fyi: I've studied this, and I did it on this very planet.

Hey Karl... do you have a video that you can recommend for proper techniques for sharpening knives.

If you strop it on leather afterwards you Polish the burr off

Absolutely ingenuous, perfect use of materials!

Very well explained and the safety message are important. Thank you for your words of wisdom on this.

The audio makes me feel like your giving away some sort grand secret.

I really need to make this! I have tons of knives that are dull and I'm just too lazy to get around to it.

Jewelers, such as I am, use a cotton wheel. These wheels can be of various densities from a jeweler's supply shop and there are wheels that are dense that you can load with rouge.

they work wonders when you're trying to to put a shiny finish but when sharpening that give will screw the bevel geometry we use leather wheels, they need some dressing and while they don't cost much for someone with dedication to sharpening, for a beginner that money may be better spent on a diamond flattening plate and some stones so the plywood might be an acceptable substitute for a while not shunning them at all tho, they put a mad shine on all the brass bits (on a side note, the truly insane sharpeners end up using extremely high grit lapping compounds designed for optical lenses and do the whole thing by hand)

@@mindbreak666 A cotton wheel is not a sharpening tool. It's for polishing. I sharpen my hand plane blades to 16,000, which enables me to take shavings less than 0.001 of an inch and leaves the wood surface burnished to a near mirror surface.

Glad to see someone online that admits to the public that whetstone honing takes considerable skill, especially concerning straight razors. I can sharpen my pocket and kitchen knives, but no luck with straight razors, and I have a Naniwa 1K, 12K, a Norton 4/8K, a DMT coarse to dress the Norton and several strops. Still no luck after 4 years on straight razors, and this is with quality one!:(-John in Texas
