Full Metal Pocket
Check out these phenomenal creations available at GadgetStorm. Dubbed "Wallet Essentials", the Visa-size metal cards fit nicely in your pocket, and can be pulled out in case of emergency. Different cards have different uses: bottle openers, metric wrenches, picture frames, ice scrapers, combs, fold-out cufflinks and dice (just in case you're hoping to lose all the contents of said wallet in a spontaneous game of sidewalk Craps). In any case it should definitely appeal to the Boy Scout in you. Of course, each "essential" will set you back about $15, but I'm pretty sure that's what all those other cards in your wallet are for.
