Let me tell you about what I do here. I make custom knives using many different materials.  All my knives are sole authorship unless stated otherwise.  All of my heat treat on carbon steel is done by me in my shop. The high carbon stainless steels and alloy steels which I currently use are being heat treated and cryo quenched by my friend and fellow knife maker Gene Martin.  

The carbon steels I prefer to use are 5160, 10XX series of steels, O1, W2 and W1. The steels I use for for pattern welding are 1095, 1084, W2, W1, 01,15N20, L6 and 8670 modified. I also use some high carbon cable, motorcycle chains, chainsaw chains and wrought iron at times, most of which are recycled. The high carbon stainless and alloy steels that I use are ATS-34, 154cm, CPM 154, 440c, D2 and A2. I am starting to use 19C27 and 13C26. I will use other steels upon request. All steel is new unless stated otherwise.  

My handle materials vary from wood, bone, antler and micarta. Some of the wood, bone and antler I use requires stabilizing and will be stated that it has been stabilized.
