"I hit the hammer hooks with a stone to equalize their lengths at .025 inch and clean'em up..."
OK the half cock hook is a true recess hook with a .012"R and a .035"flat with
radiused corners,full cock is a fish hook .030" flat sharp edge.
What is accomplished here by that modification?
You just about destroy the half cock profile and reduce the full cock at least a
good .005" and leave a square edge on it.There must be a good reason for that
of that I'm sure.
