Whether you're a handyman, a soldier, or a crazy, bomb-defusing badass, you're sure to find at least one of the Leatherman MUT Multi-Tools ($150) works for you. These multi-tools were built with the military in mind, containing specialized components for handling maintenance on the M16/AR15 family of rifles, but still contains the common tools — like screwdrivers, hammer, saw, knife, wire cutters, pliers, and, of course, a bottle opener — that regular joes care about. Opt for the EOD model and you'll get bomb-defusing tools like fuse-wire cutters and a cap crimper, so you won't be running around looking for tools, MacGruber-style.
Not content to just let a knife be a knife, the Gerber AO F.A.S.T. 3.0 Knife ($75) has a few tricks up its sleeve. Its Forward Action Spring Technology ensures the serrated edge blade is open quickly when you need it, and it also packs a bottle opener, carabiner clip, and a modified drop point that eases use when your mission is spreading, not slicing.
