When I marketed my Jerry Hill stainless broadhead a few years back,I wanted to get the hardness right so as to be able to sharpen it with a file. I took one of uncle Howard's Elephant heads to a machine shop in Birmingham and had it tested. The hardness was 47 to 49 rockwell.Stainless was chosen to keep down rusting and 420 stainless was what I needed so as to be able to get the heat treating down like most of the early carbon steel knife blades. In sharpening a broadhead with a 6 inch flat mill bastard file.Start by filing from back to point. Then turn the file backwards and using the corner of the narrow side of the file, rake it forward, creating a serrated edge, that is deadly. A blood vessle cannot roll on a serrated sharpened edge.This method turns a two blade broadhead into a six edge killing missle. I prefer killing animals rather than shaving them.Ha!Ha!Jerry Hill
