I had a great uncle who recently passed, he was a construction man, lived a blue-collar life all the way to the end. He would hunt and fish when he wasn't at the job site. With him he always had a swiss army tinker and a case stockman, sometimes pen knife as well. He used these three knives on everything, he cleaned fish and small game with the stockman and the pen knife, the tinker saw most of its use at the construction job. He didn't baby his knives either, he let debris and grit work it's way into the knives, but occasionally he would rinse them out and drop a dab of some kind of machine oil in them. I would always smell oil, metal and fish when he was working with his stockman and pen knife on the count of the "debris" he never cared too much about removing completely. The sheepsfoot knife had small knicks in the edge and had play in it as well, the pen knife wobbled a little more noticeably but these knives seen decades of use and we're still usable up until the end. real working man's knife(s).
