I called Frost this morning and ask about the steel in my German Bull knives and the Buck Creek knife. I was told by a what sounded like a very young lady she didn't know and would check with someone and get back with me. I was in a business so I didn't have access to a computer or pen and paper. When she called me back (surprised me) she said the one of German bull and the buck creek knife was 440 and the German Bull muskrat was 4116 German steel. I being caught off guard and not at home wrote these no. down. Now I'm home and trying to research these metals. I wasn't told what 440 steel it was so I've got a call back to Frost. I'm getting mixed info on the 4116GS. one sight says it for the kitchen and other said it was fair for a knife. Being new to the forum I really don't know how to research here. Any Ideas on this subject.
