Boy, pretty open ended question! Am I out camping and got lost, in which case I just gotta survive a couple days or bushwhack out? Or have I crash-landed in the jungle?
Okay, lemme define my most-likely scenario first, something I suggest everyone do before explaining their knife choice. My most-likely scenario is lost in the CA forests. Biggest danger is hypothermia as the temperature plummets at night. I will almost certainly be found or be able to bushwhack out in a couple days max. I may need to make a shelter, clear out a campsite, cut up limbs for a fire.
For this job, I'm always looking at the same compromise. Best performer at the lightest weight. In theory, Livesay's RTAK should be exactly what I want -- strong enough to handle all my requirements, thinner than most knives in this class for extra-high performance, lighter than something like the (probably more robust) Battle Mistress.
