While some people may not consider this a tool, this multi-use product has patched up a particle accelerator, made equipment repairs on the moon and been used to fashion everything from waistcoats to wallets. Yes, we're talking duct tape, one of the most inexpensive and indispensable tools a well-equipped workshop needs [source: Popular Mechanics].
Traditionally, duct tape features a 1 7/8-inch (4.8-centimeter) wide flexible, silver-colored material backed by extreme stickiness. The tape saw its first use during World War II to seal ammunition cases. It seemed to work particularly well because the polyethylene-coated tape kept moisture at bay [source: Princeton].
Today, duct tape can be purchased in a variety of colors and widths, and is a home and workshop staple. Just don't use it for actual ductwork. According to scientist Max Sherman of the Lawrence Berkeley National Laboratory, duct tape "failed reliably, and often catastrophically," when used to seal ducts [source: Sherman]. Good thing it's still a handy tool for, well, everything else.
