Cobalt makes good points. Personally, my combos have always consisted of "small fixed blade" with hatchet or large fixed blade, possibly a multitool on top of that. I've found folders pointless to bring to the woods, since they do nothing better than fixed blades of similar blade length (well, they do get dirty and fall apart "better", but I'm not sure I want that). Similarly, there's no reason for me to carry a third wheel medium size knife, when I can carry the large chopping tool instead. The large chopper will do all the big tasks, and the small fixed blade will do everything else. On the other hand, I do sometimes carry medium sized knives as the "large chopper", dropping any larger knives or hatchets off entirely. Chopping is fun and all, but if you don't want to do it because you think it's a lot of fun, there are precious few scenarios where you would actually need to do it (this is assuming that you're not going to clearing work or such, but to spend a good time in the woods). So, whether I carry a medium or a large fixed blade as the "big one" doesn't matter too much.
