I been pressure flaking slabs a lot lately so tonight I decided to do something different.
I just picked up some flakes, gravel and a section of broke biface and direct percussion knapped out some preform for some Cahokia points. The last one I worked was the gravel on the right and I don't know if it's gonna make a Cahokia. I had a good preform with it and I should have stopped, but one hit led to another until I pretty much kilt it.
Heres first flake then I decided to do them as a group
