I shot a flake of West Texas Chert into my wrist pressure flaking at this past Burlington Knapp In.
Spurted blood across the tarp.
By the time I got it staunched and CA glued up didn't know I still had the flake in there.
It came out two weeks later...
I was saving it as a Trophy, but the misses threw it away... By accident

It was about 5x6mm and Razor Sharp.
I miss that Flake.
