I carry a Benchmade daily (about 3 inches, non auto, can't remember the model though).
I keep an ESEE Izula and a replaceable blade knife (like a havalon but don't remember which one) in my kill kit. The Izula can baton wood if needed, can throw sparks for fire if needed, can skin/quarter game if needed, and can be sharpened of river rocks if needed. It's a good light weight, do everything (but not great), knife.
I have an ESEE 4 for camping duty that i'll take with me if I have a stove that needs wood chopped.
I have a few different Gransfors Bruk axes/hatchets i'll take camping (and maybe hunting if I deem necessary).
