Ah, Julia Child... the mother of the survival movement. If an overweight lady can eat like 8 or 9 thousand pounds of butter in her life and still live to like 118 (at least she looked it), then I say she was doing something right!
No real survival issues I can think of off-hand. But I use the LM Wave all the time. I use the Micra even more frequently. I also have started carrying one of LM's newer knives, though haven't used it too much as yet. Throw that in with my Becker Necker (as recommended here) and I think I'm all set. I have the Spyderco sharpener, but mostly have used diamond or fine stones. I'm only just now learning puting a new edge on vs. honing. I think I've been poorly sharpening for ages (probably ruining otherwise good equipment or letting it go in a drawer before it's time)
For survival, I think a solidly built full tang fixed blade and a sturdy multitool would serve you in most any situation. Throw in a small backup and you're set.
