I Knap a bit, I'm not a teacher by any means. I went to the Linc school of knapping. I've turned out some nice pieces but I've also made a larger pile of blood laced rubble. I'd be willing to point you in the right direction. I live pretty close and I work in Vestal. Shoot me a PM!
If you're interested theres a 2 day knapping course being held in Owego in August, teacher is Craig Ratzat.I think I'm going to that myself.
The Stone tools show is August 21-24 At Letchworth park. If you need or want tools, materials and pointers don't miss that show.
