Leatherman

Timothy S. Leatherman, a 1970 mechanical engineering graduate of Oregon State University, and his business partner, Steve Berliner, formed Leatherman Tool Group in 1983 to sell Leatherman’s first patented multi-tool prototype, called "Mr. Crunch" while in development.

Leatherman was inspired to design a "Boy Scout knife with pliers" while he and his wife traveled Europe and the Middle East in 1975, often attempting to use a simple pocketknife to repair their repeatedly malfunctioning car and leaky hotel plumbing.[2][3] He spent several years perfecting the "Mr. Crunch" prototype and received his first U.S. patent (4,238,862) in 1980. After additional refinement, Leatherman’s first product was introduced in 1983 as the Pocket Survival Tool (PST) and initially sold through Early Winters and Cabela’s mail-order catalogs.
