SOG Knives introduced the Micro, which is the smallest pocket tool in its line. Inside you'll find pliers, flat and Philips-head screwdrivers, and a file. The best part is the tool only weighs a scant three ounces—less than pocket change. You can adjust the settings on your rifle's scope, or fix those other little things you don't want to dig out a full-sized set of tools for. The micro is available in black, blue, green, and pink.
