I've seen an ol boy chip out an arrowhead once, that's a talent that's very rare these days, or at least it seems it would be. That's great work. I've lived in Oklahoma almost 40 years and I've yet to find an arrowhead, but then again I can barely find an Easter egg.been working flint for almost 40 years , frustrating hobby but has it's rewards, blacksmithing is pretty satisfying
