The Pilot's Multi-Function Hammer won't drive nails, but it might just save your life. Use the Multi-Function Survival tool to break windows and cut jammed seatbelts to escape being trapped

Being able to escape should be valuable enough, but the Multi-Function Hammer also includes a ratchet, screwdriver (Phillips and flathead), knife, bottle and can opener, saw, assorted hex wrenches, and an LED light all in a compact nylon case that fits in your pocket.

As the old adage goes, "it's better to have it and not need it, than to need it and not have it." Be prepared and have peace of mind.
