I have made different sizes of patch cutters for guys I shoot with, and members of another forum. I make .750,1.00,1.125,1.250, and 1.500
for the big bore shooters.These sizes seem to fit any need from .32 caliber and up.
I make the tools out of A2 Tool Steel. They are hardened and drawn to 59Rc., and the ends are drawn back to 45 Rc. to avoid chipping them if a metal hammer is used.
I have sold about ten of these so far and everyone seems to be pleased with them. You can cut between 20-30 patches at a time with ease.
The guys that shoot the 50 calibers like the 1.125 & 1.250.
I sell the .750-1.250 for $25.00 to your door, and the 1.500 for $30.00
