Thought? Would be nice to have a set of super vitrified diamonds or something like that in massdrop style.
Bulk discount? Fancy KKF/BBB stylized branding?Certainly something like this could be managed, but what would be the unique attraction to a massdropped stone vs. folks going and buying one at their preferred grit?
I've considered stones previously so happy to discuss the topic. Feel free to send me a PM.
I think it would have to be a set of stones. Low grit, mid grit, finisher. Seems like more and more of these higher vanadium steels around.Certainly something like this could be managed, but what would be the unique attraction to a massdropped stone vs. folks going and buying one at their preferred grit?

?Are you all aware of micro fissures due to diamond stones?
Man.... I know 1000 dollars is a deal for these stones, but man. I just literally don't have the money.I think it would have to be a set of stones. Low grit, mid grit, finisher. Seems like more and more of these higher vanadium steels around.
Some of the super vitrified stones are 450 each. Maybe a massdrop of 3 grits, $1000. I would think a lot of people would be in. But of course, BBB or someone with a supplier would need to be involved.
Obviously I do not want to divert sales from anyone, but this may be beneficial to the buyers, the middle man, and the manufacturer.
So a while back, the straight razor people started noticing that when using a DMT plate for bevel setting, chips would later form. So some mad scientist did this study about sharpening using diamonds and the conclusion is that diamonds will basically embed into the knife so deeply that the forces generated would crack the edge and form extremely tiny fissures that eventually would form a chip and depending on the hardness and material sometimes it would keep growing until it was visible. I would recommend using Diamonds for sharpening at very steep angles just to form an edge to save time but sometimes the risk is just to great when sharpening some of the higher HRC knives.

Interesting. Makes sense with plates. The bond on the abrasive is really strong with them. Curious if resin and vitrified have the same problem.So a while back, the straight razor people started noticing that when using a DMT plate for bevel setting, chips would later form.

In my experience, it still happens. It has to do with stress concentrations formed by the super sharp edges on the diamonds.Curious if resin and vitrified have the same problem.
Huh. This is a little disappointing. However, sounds like it may be less of an issue in practice for knives, but is a practical disadvantage for very fine applications like razors and optics. Really interesting points raised.
Also like someone else said, is it even necessarily noticeable on something like a knife.
For kitchen knives it's not so bad in practice, unless you want super shallow angles like the guys in the straight-razor world.
If it makes you feel any better, high carbon steel knives often have micro-cracks inside the steel. It's one of the difficulties of forming martensite.
I wouldn't get to worried, try sharpening with a ALOX stone and if you dislike the process use a diamond stone. Slurries btw have the peculiar effect of breaking down the abrasive and giving a finer finish. I haven't used cubic boron nitride, I hear it works well but never worked with it.So let's say I'm going to sharpen something like s110v, k390, or maxamet. Which is going to be more likely to cause problems for the edge then? Aluminum oxide, or diamond stones?
If you don't mind indulging me on this question. Also if diamonds cause the problem, then what would the best option be cbn? Also like someone else said, is it even necessarily noticeable on something like a knife.
Well in the case of the steels I just mentioned, I would go with resin bonded diamond (I can't afford vitrified diamond). If not then SiC at the very least. I haven't tried cbn either.I wouldn't get to worried, try sharpening with a ALOX stone and if you dislike the process use a diamond stone.
