Leatherman

The original Leatherman tool was called the PST, or known as the Pocket Survival Tool.

Eight years in the making, the PST comprised of 13 different tools and folded up into a five ounce, four inch toolbox. In the first year of business, Tim and Steve hoped to sell 4,000 tools; instead, they sold 30,000. And over the next decade, they would sell over one million PST multi-tools.
