You won't hear me bragging much about my knives, my customers do it for me. I use what I feel are the best raw materials I can find. For blade steel, my favorites are D-2, ATS-34 and CPM-440V. I carefully heat treat, freeze, triple temper and hardness test during the blade making process. If a blade doesn't meet these specs, into the garbage it goes. When you first get a new knife from me, it will be extremely sharp. Don't be disappointed if it dulls quickly, as it is actually too sharp. Resharpening one or two times will get rid of the ""wire edge"", and then the blade will really start to perform. I use diamond stones of medium and fine grit, and I recommend you do too. I like how the edge then bites into what I'm cutting. I guarantee my knives in materials and workmanship..as long as you don't abuse them!! It looks impressive, but we all know a fine blade used as a chisel becomes a lousy chisel. Knives are for cutting, not prying or turning screws.
