Gerber back pack axe.
I know, its not a knife but for wilderness chores in general it cannot be beat. You can chop limbs for fire wood, hold it like an ulu to make kindling, baton it to split wood. You can use the back like a hammer. You can dig with it, pry with it and scrape with it. Although I have never done it, you can skin with it, cut and quarter game with it. It makes a great cutter, slicer and chopper for cooking chores, again hold it like an ulu. You can carry it on your belt like a knife. Be sure to carry a small sharpening stone to freshen up the edge. The more you use it, the more uses you will find for it.
Pair it with a SAK Huntsman or Farmer and you will have all of your wilderness chores covered. Add a pruning saw and you have a modern Nesmuck trio that is tough to beat.
