Thanks for the replies. Jammed car or home doors was about all I could think of. I've been thinking of getting a Fubar for our apartment, in the event of fire or (less likely) earthquake.

Has anyone found a use for a prybar (or a knife overbuilt so as to be usable as one) in a back woods / outdoor scenario? I'm kind of stumped there. I don't think there's much to pry, except maybe breaking into a building for emergency shelter, which is probably a pretty low likelihood situation.
