Greetings BUCK fans
: I just came across a BUCK model # 137 Steelmaster sharpening tool in a trade recently. This is not the first one of these I've found. It is apparently a sharpening tool meant for steeling and to a limited degree abrading and sharpening a blade as well.
I've seen a lot of BUCK products in my days but this #137 "Steelmaster" is a rare bird of sorts. I'm just wondering if any of you hard core BUCK fans could tell me a little more about this item?
It even has a Chisel looking end on it and comes in a very handsome leather/belt carrying case. I've had some of BUCK's sharpening stones in the past and I will admit that they always used a very high quality of novaculite in their stones. But I don't have much of a clue as to what this tool is intended for other than what I just described. And am I right that it's a rare item?
