One of the nice things about knives is you can carry a lot of them. It'd take an insane number of decent sized knives to encumber you significantly if you know how to carry them, and different types do different things better. I'd go with the Kukhuri for compact efficient chopping, and a drop point skinner for just about everything else.
If I had to pick one blade for wood survival, it'd have to be a bowie, you can't argue with over a century of use. It's been around longer than centerfire cartridges, for christ's sake, and still going strong. A good one is damn near indestructable, can skin, chop kindling, shave bark, and in a pinch be made into a boar spear.
Sure, you can tack on all kinds of widgets, cadgets, special serrations, etc, but for toughness, and utility, you can't beat a Bowie.
