All knives are hand ground from start to finish with no water jetting or cnc so each blade is unique. Heat Treating is done by the awesome staff at Paul Bos. I use CPM 154 for most of my blades but I am trying some Nitrogen stainless steel for some neck knives right now.
Every DIrte Knife comes with a lifetime guarantee and a lifetime of free sharpening! You send it to me and i'll send it back.
