It seems to be one of those skills that was crucial to our development as a species. My understanding is that a well crafted knife can be sharper then any metal blade. Ok, well, maybe not Horndog's...
much sharper... the flake, as I understand it, is at the molecular level.... I heard from some guys that worked for me that were amateur palentolgists there was a surgeon somewhere that developed surgical tools he believed were sharper that any steel available... he could not get approval to use them in surgery, and by happenstance had them used a at later surgery performed on his own body.... might just be a BS urban legend..... but was an interesting conversation....
