More SEM images from The Science of Sharp

Interesting. What a big box of worms

Thanks! This is a truely great blog!

But I think that the DMT plates work completely differently than the Wicked Edge ones, although i may be wrong =)

I agree 😆 . I particularly like the sentence

The reader could be forgiven for concluding that these results make no sense…

I’ve decided to stop theorizing about sharpening for at least a week 🙂 .

Ohh my… :S

I totally understand how the scratches could be deeper and more prevalent in the finer grit because of the higher force applied on such a smaller area but the fact is you remove more metal with the lower grit faster…So maybe it is like you are shoveling with a snow shovel on dirt vs a pole hole shovel…

What gets me is that I really would think the teeth on the apex would be wider with the low grit and start to get more narrow and more prevalent with the finer grit. wide tooth comb vs fine tooth comb thing… So it would be interesting to see what happens with edge

–ok wait..I wanted to use a word to describe a term..but I do not know which to use Keen ness. vs sharp vs cutabillity.. I gotta be careful with my words..I understand that for a shave you want the apex not real toothy and wavy.

but what happens with the apex at these progressions if a light strop or light refining with a super fine ceramic is done after each? I am gonna have to get involved in his posts. Super great and curious work.
