I had a preform made out of a pc of Kentucky hornstone, flat on one side with a slight hump on the other, had a fracture part
way across on the hump side. I just kept thinning hopeing to get under fracture seeing as I couldn't see it on the flat side
, kept thinning and finally got below fracture and ended up with this nice Snyders. Hope ya like it and thanks for lookin. Bob
