I have a knife for on the water - a serrated Gerber that clips to the outside of my lifejacket.

I went with the ka-bar as one of the cheapest fixed-blade knives that I trust to hold up to batoning through wood. The 5 1/4" version also fits in my drybag without taking up too much space.

Good point on fitting stuff in my pockets. I'll plan on sticking a spark-lite and some tinder in a pocket. I also have some waterproof tape and bandages in there for blisters, but doubt I can fit much more in. My lifejacket has very limited pocket space.

I'll toss my water bottle into a fire on my next camping trip - make sure it holds up before I'm depending on it!
