Thanks Chris for your kind words. I have no idea what the properties are this stainless, I'd say it is 416, since this was a bargain priced knife. I had a bit of experience with all types materials while working in the printing industry. It doesn't work like a hardened material. It responded very smoothly is why I must assume that it's probably 416. The only # is the model #525, the local hardware store had a boat load at a reduced price. A small investment to play, now I'd better get back to finishing the paying jobs.
Fare well,
Mark
