I made this patch cutter for a shooter but it came out larger than what he wanted SO I am offering it up for sale for $50 not including the price of shipping to the lower 48 US states. Here is a picture of it and the three patches that I cut with it out of 0.023" patching material. using my drill press. The drive shank is 7/16" hex and is torqued and staked in with JB Weld.
