Well, this is going to be a long thread, as I am only at a first stage - finalizing testing for a heat treat. I need to ran one more test, and after that, I am going to attempt three knives in different length.
Steel - 52100, target hardness of the finished product - 62. Objective - a good balance between edge stability and abrasion resistance, and of course, a knife's ability to take a keen edge. Will keep you posted and post some pics.
All work is done in-house by me.
