I started this one awhile ago. It was something I got from Frank at the Michigan Primitive meet.
I had a rough biface started with a few problems that I didn’t like at the time and put it in my to be continued cup.
I finished it up yesterday. Worked better than I remembered but still not perfect. Pretty decent though and I am happy with it.
I don’t know what it is. I think it’s some kind of raw chert. It should make a really durable Atlatl point
