For the trapper/stockman with the combination of stag and carbon steel, only a few come to mind: Eye Brand and Bulldog. They are not that expensive, with some online retailers and sometimes on ebay you can get them for aroung $50. Boker makes good ones with rosewood or bone and carbon steel blades, as well as with stag and stainless (440C). I used to see Kissing Crane slipjoints with stag and good carbon steel, I don't know if they make them any more. They do show up on ebay. Case makes bone-handled slipjoints with carbon steel, their chrome-vanadium is a good steel. I haven't used their stainless, and I haven't heard many good things about it. If you have some money to burn look at Whitewing knives, I have heard that they are really nice. They have CPM3V blades and are ground very thin.
