I am working on a few more CPMD2 S/E's except the steel of choice is going to be high carbon 1095. Although a relatively inexpensive steel 1095 has so much to offer. When heat treated properly 1095 can really come through as a dependable knife with a great edge which is easy to maintain in the field. The one and only downside is it will rust up quick. I have begun to cut and shape 5 blades 3 are 5+ inches and 2 are 4".
I will be doing a process called "differential hardening" its the process in where you use a "santanite refractory" cement/clay. When place along the upper sides and spine of knife it acts as a insulator during the heat treat process. When the knife is brought up to optimized heat then quenched in oil, the clay absorbs or retards the cooling cycle and you end up with a "temper line the bottom edge (cutting ) is very hard and the back or spine is slightly softer. It will also produce what is called a Hamon pronounced ( Ha mon ) which can be called functional art. More to follow.
Off to the post office later to ship some SAR Global tools around the globe.
