I spoke with Larry Dula, Lenoir N.C. concerning the custom knife I purchased. He says the steel is a "high carbon" steel that is referred to as "1011". He purchases it from a West Virginia Knife maker named "Wilson". Dula says the steel is a quite good steel that he hardens 58 Rockwell and it holds an edge very well. People usually skin about 4 deer before sharpening a knife made of "1011". He assures me that it is a high carbon steel. He says the steel is used in "Spark Plug" manufacturing (but I wouldn't think a high carbon steel would be used in that application??). Hopefully there is some type of steel designation that is un-usual being used in this instance. As it trully would be a shame for someone to waste the time, effort, and money to make a knife this nice from trash steel. He has no address or info. on Wilson the West Virginia knife maker. He thought Wilson may work as a some type of steel salesman when not making knives. Any input or comments would be appreciated. Still looking for info on "1011" steel.
