Depends on whether I'm day-tripping, backpacking, car camping, etc. In general, I break down uses into 3 categories: big jobs, small jobs, and equipment fix-up.
Small jobs are 90+ percent of my blade use. Food prep especially, plus whittling walking sticks or marshmellow sticks, cutting bandages or moleskin, cutting cordage, and other miscellaneous small jobs. A.G. Russell Deerhunter is my top knife in this category easily. 4" flat-ground ultra-thin drop-point blade with the most useful sheath for camping in the history of the universe. The small-job knife should have a thin edge and cut like crazy. I'm going to take a TTKK out to the woods this year instead of the Deerhunter and see how it works out -- I think it'll work excellent from what I've seen so far. I've also used a puukko in this role. Don't have a Spyderco Moran, but it too would seem to be a very strong candidate.
Big jobs include cutting kindling to size, clearing, etc. In all honesty in the northern california wilds there's very little need for this, and low-impact camping guidelines preclude this at most places. But I do bring and use a big-job knife when I do this kind of stuff. 12" Ontario machete is my fave, I've also brought an Estwing hatchet (too heavy for the performance). A kukri might be a heavier but nice choice here. I probably will stick with the machete, but if I actually did more chopping and splitting in the woods I'd seriously consider the kukhri.
Equipment fixup is anything from the stove to the tent or anything else. I bring a Leatherman PST II for this job. Most importantly, it is reasonably small and light. It has all the tools I need, including scissors which are important. And needlenose pliers are best for little job fix-ups.
Current line-up: Deerhunter, 12" machete, PST II.
Possible future line-up: TTKK, 15" Ang Khola, PST II.
