Gunsmithing, blacksmithing, and leatherwork too. I'm not really going all that far off the mark when you consider that firearms need holsters, knives require sheaths and everything rides on a belt. So, I decided why not learn to create the leatherwork needed to keep both my gear and my customers' gear safe. And, while I'm at it, why not learn how to carve and tool the leather so it's totally custom.
