Convex grind is a very common grind. Especially among custom knives. Appleseed edges look great on a convex grind also. Interesting video. First I’ve seen a buffer used to achieve an edge .
I've been watching a lot of knife making videos lately as I hope to get into the hobby soon. 95% of what I know about the science of how a knife edge actually works, I've just learnt from you. I'm very grateful for your time and effort. You just scored another subscriber.
This aren't new informations to me but despite your young age, you have a talent to explain without complicate things. Very nice to see a young men knowing what he is talking about, and passing the information with ease. 👍
Very interesting video, we have been selling buffing wheels for 12 years and I learned something new from you (how to sharpen an Apple seed edge), good job! very informative
I've gone through at least 10 videos online on how to learn this skill. All those videos are old men going on and on about things I don't know about and all these complex methods.Pkus they barly showed what they did and how they achieved it and the little things you have to do. This is a thorough simplification of these videos in a clean, understandable form for every level to learn. 10/10
Thank you! I had exactly the same problem you mentioned when I was trying to learn, so this is one of the videos where I was making what I wish I would have had to go off of 😂
1st video that I have seen that describes the Appleseed edge and how to easily obtain it. This is the same Also used on high end diving knifes which are usually quite thick.
I enjoyed your video on buffing edges and informing people on the basics of buffing. You mention the wheel throwing debris everywhere and the need for proper safety equipment. Regardless of my next question, safety is paramount. Here is my question: Most buffing machines, from jeweler's machines to industrial applications, turn at 1750 rpm, half that of a regular bench grinder. They do this to reduce the loss of rubbing compound through centrifugal force, and to give the operator more control when using the rougher compounds. Why do you prefer motors that turn at or above 3000 RPM?
It's a complicated mix of the loss of rpms when force is applied, and the need to have as many rpms as you can efficiently get in a smaller amount of time. I'm going to use extreme numbers to try and explain more easily. When buffing knives you're trying to remove material from hardened steel with nothing but cloth, wax, and a minute amount of tiny grit. If you were to lay out the surface area of the buffing wheel, and drag the blade from one end to the other as if you were stropping/honing it, (i.e. the equivalent of one rotation of the wheel) you would not be able to notice any change on the blade. Now imagine if that strip, (the surface area of the buffing wheel) was a mile long. You would definitely be able to notice a change on the blade after dragging it for a mile. But if you're only dragging that knife fast enough to cover one foot per minute, it's gonna take you 5,280 minutes to cover that distance. So, you use a machine that will cover that distance faster, and give you noticeable results in less time. The more surface area covered in the least amount of time possible is what you're looking for, because you're taking away so little material that on a molecular level you are actual dragging more particles than you are removing, so it would be an incredibly slow process otherwise. Just keep in mind that the concept of more speed applies to polishing compounds, and not grinding compounds. A 120 grit compound has more grit, removes more material, and has more mass. So, there's no need to go faster because of how much you remover per rotation, and the mass would cause loss of compound at higher rpms due to centrifugal force. Sorry for the long explanation, it's a bit complicated to try and define it because it's just something that I do without thinking about it most of the time.
Oh, and as far as the comparison to other buffing machines, jewlers buffing machines are usually dealing with softer metals, so they see more removal per rotation than hardened steel, and want to avoid the heat from higher rpms. I've never heard of industrial buffing machines before, but my assumption would be they are running lower rpms because they are trying to remove more material faster with lower grit compound, and like you said, don't want to fling it off.
That was most informative Stanley's Steel, thanks for the demo. The coarse compound is 240 grit, the medium is ? and the polishing compound is ? Could you let me know please, I am , and always have been interested in knife sharpening. You've got a nice setup there with a heater as well. Do you know anything about the French Opinel knives which appear to have only one grind on each side? Best regards.
The compounds aren't as much classified by their grit count, except for the roughest grits of compound. It does make searching for the right compound a little different, but it is kinda easier. Jantz knife supply is where I get most of mine, and they are descriptive of what compound has what level of grit in terms of "roughing compound, polishing compound, scratchless finishing compound". I haven't ever heard of that type of knife, but if it is similar to a single sided straight razor, then you follow the same process with the exception of ignoring the flat side entirely as you don't want to throw off the shaving accuracy. If you notice a rolling of the edge or any burrs, then you can very carefully and gently do one or two passes, but you don't want to remove any material from the flat side.
Smaller blades can be a real challenge. You gotta be super careful. What I usually do is take one buffing wheel that is the medium jean-like material, and load it up heavily with the medium compound. You want to get it to the point where the surface of the wheel is almost a smooth/solid surface rather than soft cloth. Then you can carefully support the blade by pressing it against the length of your finger 👉 like a shelf, and work with it that way. When you want to do the final sharpening, you can just add the final compound untop of the medium compound, and it should still work just fine. If you're gonna do this, make sure you have water nearby because the blade will get hot fast, and you don't want to ruin the heat-treat of the metal or burn yourself. You can sometimes use this method on pocket knives, but NEVER on a blade that doesn't lock in to place. Be EXTREMELY careful about not letting the spine of the blade contact the wheel, because it WILL grab and throw the blade and/or cut you. It is a very delicate process, but with time and practice it's very doable. Best of luck and stay safe! 🙂 Lol, I might end up needing to make a video of sharpening pocket knives
Heya, I do not know the specific grit of each, but here is the link to both for more details 🫡 Black Compound: knifemaking.com/products/la855-black-magic White Compound: knifemaking.com/products/lm4-4-oz-white-rouge
Hmmm, that's a difficult one. Buffing handles is allot more finicky because it's more about how much/little and type of compound you use. A good muslin wheel works for both metal and wood, with enough play for the wood, but enough stiffness for the metal. You just have to make sure that you use polishes that have little to no grit in them, and be VERY careful about any compound that has a color to it. There are red and white and green compounds, and if the grain of the wood is to open, it will get those pigments all up in those pits, giving your handle a nasty look. So I would say go with a muslin wheel and a neutral colored compound that has little to no grit in it 🙂👍
@@StanleysSteel thanks heaps mate. That clears it up a fair bit. I don't use the same wheels for wood and metal, so would an even looser wheel suit the handles better given it doesn't need to work on metal?
@@StanleysSteel thanks mate. Appreciate longer videos like this explaining why you do something, not just a quick run through. The algorithm won't reward you for it, but it helps. All the best.
Thank you! Unfortunately keeping links active and accurate is not very realistic because things are always going in and out of stock. As long as you get the general idea of what you need, you should be able to find them pretty easily.
@@StanleysSteel I guess thanks, but currently i just purchased a buffer machine/ and I can purchase the wheels, but cannot get much info as to the compounds grit structure or strength?, I am looking at jantz and sharpening supplies? Any info you can tell me about that red compound you show would b appreciated.. Thanks again
You're on the right track with Jantz, that's where I get most of my stuff. I'm sorry that I am not being more help, I am in the middle of moving and just drove from 146am to 951pm, lots going on, so tracking down and sharing those links seems like a monumental task at the moment 😅
Appleseed is convex bevel grind correct? It can be accomplished on a stone by grinding a "wedge edge", as you call it, then remove shoulder by lowering the angle and allow some flex in the wrist. Like so czcams.com/video/UhD6gb2Dako/video.html I don't have experience in machine sharpening, but I am curious about it. Do you have any idea what level of sharpness you are able to get BESS score etc? EDIT: to elatorate, the problem as I understand it with a soft medium sharpening is that the apex should be be two planes meeting at a sharp angle, but the soft medium can overshoot and round over the apex. So the result isn't as sharp as possible.
The challenge with using a stone to form/rework/sharpen a convex edge is that it is entirely dependent on the person sharpening being able to repeatably start and stop each stroke at specific angles. Some people find it very intuitive, and can develop that skill in under an hour, other people find it incredibly frustrating and end up ruining the edge of what they're sharpening so many times the give up. It's even harder on a grinding wheel, as material is being removed very fast, and its physically awkward on smaller wheels (I find 12" to be the best practical size you can still have in a home workshop, but there's a reason the grinding hull of a cutlers workshop in days gone by retained the use of +4' diameter wheels they sat astride, long after the introduction of electric motors). I was initially taught how to do it with wood chisels and carving tools, and would never go back to double-bevel grinds now. Achieving the same result with a knife requires a lot more skill by comparison, but totally worth it.
Interesting... most videos are showing 'normal' edge bevels... You are showing how to maintain a compound bevel? or turn into one?? It wouldve been nice to see you remove the chips in the blade though...
This is the medium grit: knifemaking.com/products/la855-black-magic And this is the light buffing compound:knifemaking.com/products/la810-3-lb-pink-scratchless
@@StanleysSteel Thank you for your rapid response. Do you have a product link to the "rough" 240 grit compound? I didn't see a product on that website that listed it as 220 grit.
So it is a different type of compound called "greaseless" and it has to be kept refrigerated, and when applied to the wheel it needs to be given plenty of time to dry, like overnight. It looks like the 240 grit is out of stock, but you can select from other grits. knifemaking.com/products/greaseless-bar-compound?variant=40543929893000
No, I believe they have seperate purposes. Emery compound is a more aggressive grease compound, whereas Black Magic is a milder compound that removes scratches from other compounds. To be clear I am assuming you meant Emery compound? There is an Avery Abrasives company out there, but I am not familiar with their products, and Emery compound is quite common.
@@StanleysSteel perfect Thankyou so much. The reason I’m asking is because the greaseless compound you recommend is out of stock.

Yes, unfortunately the aggressive greaseless are used the most and therefore go out of stock more often. Your second best option would be this *.

@@StanleysSteel I appreciate your reply and I’m actuslly gonnna give it a try based on your recommendation and description. Since I use the grinder a lot it might actually be beneficial one way or another. Hopefully you can answer this last question. Have you tried their brush on compounds? Or have any info on them? I was thinking maybe The 600- 800 grit brush on compound might work.
So, I used to use those, but I found them to be much like sanding belts in the way that it wears off and stops having good effects pretty fast. The problem is that, as advertised, it doesn't fling off, and it kinda ends up ruining the wheel. You have to use a rake cleaner to remove the old compound and put on new, which wears out the wheel so much faster that normal compounds.
The problem with those tests is that they can be a bit deceiving and arbitrary. Any decently sharp knife will cut a tomatoe or slice paper or any of those tests, but only knives with specific geometry, (like a super thin kitchen knife) will be able to do those extremely thin and consistent tomatoe/carrot/whateverelse cuts.

What matters the most is that you're able to get the knife sharp enough do what you need to with it. I'm sorry for the let down, but hopefully that explains things a little.
