No wonder we have global warming, hey didn't recycle.

“It’s a simple tool where you have a certain kind of rock, and you drop that rock on another rock and a flake comes off.”

That’s the extent of my knapping skill. My boy wanted to try skinning an elk with such a chip, so I banged on an obsidian nodule until I got a large comfortable chip with one incredible razor edge. And did that thing ever slice and skin an elk! It would run up the inside of a leg faster than a knife.

Of course then he wanted some points for the longbow I made him. That was embarrassing. We did manage to get one that was roughly triangular, with one extra side, and he was satisfied to see it on his cedar arrow.
