Buck 760GRX Summit Knife
The utility of Swiss Army Knives is great, but their bulk isn't. If you plan on carrying around a multi-use knife in your pocket, check out this Buck 760GRX Summit Knife ($75). Co-developed with outdoorsman Peter Whittaker, the knife attaches easily to a carabiner or lanyard, and includes a 2 1/2" blade, a corkscrew, and a bottle opener.
