Total information screw up! I contacted Mr. Wilson who supplied the steel to Dula. It is 52100 Ball Bearing Steel as used by "Black Jack Knives" and "Marbles". Thankfully it wasn't 1011 nor spark plug steel. Mr. Wilson was very helpfull and contacted Mr. Dula to clarify the steel information. So in the end I'm satisfied with the knife, the steel, and the maker. Thank all of you for the help you gave. I would have never been able to locate Mr. Wilson without this board. Thank you again. Best regards and have a great day.
