My short answer would be the Fallkniven F1. I feel this is a near-perfect all-around outdoors knife that is more than tough enough for any survival situation you could find yourself in.



For a more detailed explanation of why I choose this knife, check out a post of mine from a couple years back: Choosing MY knife. It outlines the attributes I felt were important in a knife and ultimately how that led me to the F1. Of course, you may have some different needs or priorities than me which may make the near-perfect knife for me less than optimal for you. For example, I'm not a hunter so I don't know how to judge how well this particular knife would fit in that role.
