Obsidian
Actually, it is so sharp--a width of one molecule is possible at the
edge, I believe -- that cuts from it heal very fast. Moreover, you hardly
notice it when you cut yourself with it.
I have been trying to work a piece into shape when I've noticed
blood all over the piece and my fingers--yet having felt NO pain; then
very quickly the blood flow stops. Within a day I cannot see any trace of
the cut.
