Heres some more:
This first pic is a flat tab of another type of killer
The second pic is a small piece I just had to try out.
It flaked like a dream. I had it going real well but neaded a flake to travel from midway on one edge into the base area to under cut some crumbled area there and I hit too far in and broke it.
I have found my new favorite rock to knap for a while though. If heat made that rock any better I don't think I could stand it.
I had to pry myself away after that. I am working on my christmas exchange gift, but Man! I sure was tempted to get another rock and go at it.
THANKS! Knapperhead. You fixed me up with some KILLER rocks. MERRY CHRISTMAS everyone.
