Ok, I want to add a post to this topic about heat treat because this has come up. Two Saturday's ago I called Paul Bos of Buck Knives (ret.) and discussed with him the heat treating of Buck's slip joint knives. During our rambling conversation about the steels used on these models and their heat treatment, Mr. Bos said that he had Rockwell tested many of the contract Camillus knives and their heat treatment was sound. The readings ran 56-58rc, off the top of his head. I carry and use one of my Camillus large Trapper, md. 334 and I think it cuts & holds it's edge great. Likely around 58, and sharpens up real nice. Thus, I think a quality product. DM
