I designed it, Jim Rosa ground it and I did the handle. Its in full hardness .150 thick M390. Its also hands down the best knife Ive ever used in terms of actually cutting ability and comfort. Jim absolutely nailed it out of the park and I had an all around awesome experience with him helping me bring this concept to life. He's a stand up dude and runs his business with integrity.
I'm having him make me a couple more. Maybe I can get a pass around going with one of them.
