The Leatherman Super Tool was introduced in 1994, with a saber blade, L-shaped screwdrivers, no hard-wire notch, and USA on the plier pivots. It had a very heavy-duty set of pliers that was reduced in size a couple years later. The same tools continued into early 1995.
August is the earliest date that we've seen stamped on the handles for the 1994 Super Tool. Because of the relatively short production year, this introductory model is much less common than succeeding years.
