My go-to’s are a Outdoor Edge replaceable (I resharpen the blades and get many uses out of them) with that long European gut hook thing along with a folding fillet knife. A little overkill, but they speed up processing an elk for me. I have a Helle Polar strapped to the outside of my pack for general use and skinning. The Helle gets replaced with a slightly larger traditional Roselli knife when it’s really cold (they are both fairly light, but only the bigger knife is good for batoning wood and generally breaking down an animal). When it is really cold, those traditional wooden-handled Scandinavian knives are great; the birch handles don’t draw the warmth out of your hands like hard rubber, micarta, or (and here I shudder) aluminum. There’s a Victorinox boning knife in the truck, and I usually keep a small neck knife and ferro rod in my bino pack. That’s a lot of knives, but I rarely have to sharpen in the field and can get a fire going in bad conditions.
