My Sig. Seriously, I'm not floating something that would require anything like a "wilderness" rescue, so I've got patch stuff, spare oarlock, first aid, and that's about it. Get me out in the forest though, and that's a completely different story. There, I've got my hunting knife, sharpener, rain shell, firestarting materials, emergency food, water, small 1st aid stuff, whistle, 550 cord, multi-tool, and a hunter's axe. There's nothing I can't make with that stuff.
