I keep a Buck 119 in my pack as a "just in case" knife. It's not a purpose-built survival knife, but it's a pretty good size and I like the blade profile. I bought it because the price was too good to pass up (around $40 new in package) and because I like Buck knives in general, and it's dead handy camping. Between it and the hobo knife that live in my pack, along with whatever happens to be in my pocket (generally either a Buck 301 or 307 and/or an Endura 4) I think I could be a lot worse off.
