I was digging through some rock I've had stashed away last weekend. I came across a box of untreated stone stringman sent me months ago. I threw a few pieces in the roaster with some local stone,& was pleased with its workability. It knaps a little different than Tx rock, but its very good stone. Since it was something different, I thought I'd make a different style point. I hope everyone enjoys them. I've been working on some flintridge flakes given to me last spring. I'll try to post them tomorrow. Tower
