I just started carrying a PSK in an Altoids tin and now I feel odd if I don't have it. It doesn't take up much space and would be helpful in an urban or wilderness environment. It may help some people get one together, or it may give others ideas they didn't think of before. Myself, I did my first one last week. My PSK currently consists of (from Bottom L to R to Top): 2 Alcohol Swabs, Flashlight(led and two batteries), Leatherman Micra, Foil (about 12"x12"), 2 Immodium AD & 2 Benedryl, Nail file, SOL TInder-Quik, SOL Striker, Duct Tape on straw, Nail w/ 30' of 30lb Braided Fishing line, 2 small nails, Flat Whistle, 4 waterproof matches, 4 bandaids, 3 butterfly closures, and Altoids Tin w/ 2 utility blades taped to the lid. "Ranger Band" is a bike inner tube to keep it from opening. I still need to add a button compass (Tru-nord 100C), a few needles and thread, a strike pad for the matches, two Tylenol, and safety pins. I may have to figure something out to get that all in there. I also plan to add a Zippo to my EDC as it seems like it could be handy for many things.
