Everybody has their own opinion on what makes a good camping and outdoor knife.
Some think that you need a multi-tool to fix gear. Frankly, I usually have one with me when I'm adventure camping, (specifically, a Leatherman Surge), to help with vehicle and gear repairs, but I don't carry one when camping or backpacking. I find they are too bulky and heavy on my belt to carry when hiking and backpacking. I could keep a multi-tool in my pack, but then what good would it do me if I am separated from my pack when I need it? And, in the woods, most of the tools (and therefore, weight) on a multi-tool provide no benefit, unless you are driving a Jeep, quad or other off-road vehicle, (and even then, I'd prefer real hand tools to a multi-tool).
Others believe a good camping/outdoor knife should be a medium fixed-blade knife capable of chopping and batoning wood for shelter and fire in an emergency. Something like a Short Ka-Bar, Ontario RAT-5 or Gerber LMF-II fixed-blade knife. My problem with this is the same as a multi-tool: it is not comfortable to keep on my belt, and so it's effectiveness as a survival tool is lost if I'm separated from my pack.
Most hikers and backpackers go with something that's easily carried in their pocket but can provide some basic necessities beyond a good knife blade. A Swiss Army Knife fills this bill nicely, as does some of the smaller Leatherman multi-tools. Things like a toothpick and tweezers see a lot more use than files and screwdrivers on the trails.
Ultimately you need to decide what your philosophy will be on knife carry. I developed mine through 35+ years of backpacking, hiking, camping, off-roading and daily carry. Throughout this process I've collected about 30 different knives and multi-tools. The one I carry every day, to the office and to the woods, is a Victorinox Swiss Army Compact.
