Grunt you took the words out of my mouth, I was going to suggest a Swiss Army knife, but along with the lighter, I would add a magnesium bar. It will light damp wood, and the sparker on the side of it will also ignite paper, and can be used as a signaling device, and might even scare off nosey critters......I would take about three inches of an old hack saw blade, grind a single bevel on one side, and a chisel edge on the end, to use on the striker, and for shaving off slivers of magnesium, so you don't ruin the edge on your knife. I agree with the extra bow string, and extra string, and fishing hooks, and line, maybe a small spoon type lure, or spinner, in an Altoids can, with some toilet papper inside, and wrapped around it, and in a small zip lock bag, and like it was already said, a large, heavy duty garbage bag, which could be used as a rain coat, water proofing a lean to, etc. I would take at least two of them, lots of uses. Oh, and of course the every survival mans greatest tool, "Duct Tape". That's where the extra pouch could come in handy, maybe near the top. Simple quivers, are probably the most useful and convenient. You don't worry so much about them getting dirty, snagged, stained, etc.
