I disagree somewhat with the notion that you can't pick your survival knife. True, no one PLANS on getting into a life or death situation. But, anytime you are willingly and knowingly putting yourself at some risk, (say for instance, that you are going to Canada and be flown into a lake deep in the interior of the north woods for some fly fishing), Then I think you would be foolish to not consider the possibility, however remote, that everything could go wrong. Then a prudent person would choose which of his knives to take, which compass, etc. Generally, whenever a person gets lost in the woods; stranded in the desert, or whatever, they have played some major role in getting themselves into that situation. But, usually went into it without thinking about possibilities and with poor planning.
