Ah, the Leatherman Signal, an "I'm going off-the-grid to fight the zombie apocalypse" survival multi-purpose tool. Though it contains all of the traditional necessities such as needle-nose pliers, wire cutters, regular pliers, knife, a wire stripper, can opener, bottle opener and carabiner clip, the Signal also includes a safety whistle, ferrocerium firestarting rod, diamond sharpener, saw, hammer, 0.25 in. hex bit driver, bit driver, 0.25 in. box wrench, and 0.187 in. box wrench. Whether you're a hardcore survivalist or former Scout, the Signal will allow you to both call for help from under the rubble during the impending WWIII or open an ice cold pilsner by the campfire. Now that's what we call a multi-purpose tool. We never leave for an overnight hiking trip without our Signal.
