We shot one with a 9mm one time and I gave the broken pieces to Jeff. (not for warranty, of course) This was in the old days, though. Prior to Rowen. It was part of an absolute destructive abuse test. I can't find the write-up right now but it involved trying to burn the micarta off with a lighter, breaking MANY car windows, cutting through car doors, truck tires, chopping concrete blocks, body armor, etc. I'm actually glad that the knife broke because we had some det cord to wrap around it if it survived that test and the shrapnel probably would have killed us all--Remember that, Jeff?
Maybe one day I'll do it again with a Rowen made one. The Ontario one held up surprisingly well so I know that the Rowen one would be killer.
