One Cool Tool I've got other multitools; however, this is the one I take to the field. At 4 ounces and 2 inches when folded, the Leatherman Mini-Tool is half the weight and size of all my other multitools, yet it opens up to make a full-size pair of pliers. And, it's got all the other gizmos you really need: knife, file, screwdrivers, can and bottle openers--the works. Price: $34. 800-253-7826; www.leathermantool.com.
