Leatherman is an American brand of multitools and knives made by Leatherman Tool Group of Portland, Oregon. The company was founded in July 1983 by Timothy S. Leatherman and Steve Berliner in order to market his idea of a capable, easily portable hand tool with multiple functions. That same year Leatherman sold the first multitool, which was called the PST (Pocket Survival Tool).

Leatherman’s primary products are multi-tools and knives. Most Leatherman multi-tools are built around a pair of pliers, with up to 21 additional tools stored in the handles, including knives (straight and serrated blades), screwdrivers (flat, Phillips), saws, wire cutters and strippers, electrical crimper, bottle opener, and can opener. Most models have a built-in safety mechanism that locks the active tool in the open position when fully unfolded. Models range in weight from the 12.5 ounce (335 g) Surge to 0.81 ounce (23 g) Style.
