Weighing a mere 1.58 ounces, the stainless steel, three-inch Leatherman Style PS lets you pocket eight tools, including pliers, a wire cutter, small scissors, tweezers, a file, and both Phillips- and flat-head screwdrivers. On a recent hike, it proved well suited to such tasks as servicing backcountry stoves and straightening bent bike spokes. One drawback: The PS lacks a simple knife blade. If you need one, you can trade up to the CS model, which drops the pliers in favor of beefier scissors and the addition of a knife blade. The CS weighs 1.4 ounces and works better as a simple camp tool, where the ability to cut cleanly through a variety of materials comes in handy. [$20 and $25 respectively, leatherman.com]
