hey dudes. i haven't done a real thorough search to see if somebody already suggested this, so sorry if it's repetitive. anyway, i used to keep a PSK in the traditional altoids tin, but that just didn't seem to water-tight or durable to me. i got one of the small otter boxes (after having seen what bigger ones that i have can stand up to) and i'm now using that as the container. it's waterproof(bouyant when fully packed too), and definitely crushproof (and in high-visibility yellow!). the inside volume is a little bit bigger than the tin, which can be looked at as good or bad (of course, i filled it so much that i have to put a strap around the outside to keep it sealed : ) ). i even found a small lockblade that's made out of two flat pieces that i can fit in there with everything else. i just thought some of you guys might want to check it out. the box is here
