For most of us the wallet is a place for money and credit cards, but for the gadgeteer no pocket or compartment is too small for another timesaving or practical device. Your gadgeteer can’t fit a tool kit in their wallet, but with a survival card he or she can have all the benefits of a Swiss Army knife minus the bulk. The “Silver Streak” survivor card includes, among other things, a signal mirror, screwdriver corner, wrench, ruler, bottle and can opener, and 1” or 1.25” blade.
