I will look at the electron tunneling images if I can find them. Haven't tried yet. Thanks Lostconjugate, nice imagery:) You seem to be a bunch of very nice folks here, despite my antiquated and very rusty training:)

Thanks again for the replies folks:) Another small nugget of understanding came to me:) I have to let you kind folks know I'm pretty good at making an edge razor sharp. With some of the newer powdered metal materials I have on hand posess a very fine grain structure and keep the edge very...

oxDEADBEEF, this means that the ripping is more likely to occur at the defects?

Thanks for all of the replies folks. They are appreciated. I believe I didn't make my initial query quite specific enough. This probably involves more metallurgy than pure physics, but I believe any knife steel alloy consists of lattices of iron and the alloying materials held together by...

Thanks Turbo-1 for your reply. I do know how to get the knives sharp and what not to do while working them. I'm curious as to what's going on at a very small scale (nano) as I'm sharpening them. This is a purely theoretical excersize on my part. Where in the overall structure of the metal...

Hello folks, my study of physics is 20 years old or so please bear with me. I enjoy sharp knives and blades in general and am curious about what is actually happening when I sharpen them. I know these steels are a matrix composed of different elements tightly bound by nuclear forces, but I'm...
