Perry, I didn't think about the material that might have been used, but you very well could be right. He worked at a steel mill that makes roller bearings and stainless steel, among other products. I've never seen anything like it, not that I'm terribly experienced. But I HAVE seen alot of abused pieces.
What about era? I can't get over the raised "8". I've always considered raised letters and numbers like this a sign of age, but nothing else about this piece indicates an 1800's piece.
