Heh, me? A natural? Hardly. I didn't show you the ones I busted while trying to make them. Plus, you can't see the all step fractures in that picture, but they are obvious when you look at them in person. Those five heads probably account for well over 10 hours of breaking rocks.
I'm in NYS, and according to my reading the heads have to be at least 7/8ths inch wide, which the last head is, they can't be barbed, and they have to have 2 cutting edges.
I made the pressure flaker, but I'm going to make an Ishi stick for pressure flaking because it's hard to run a good flake with that small flaker.
