A multi-tool (or multitool) is a hand tool that combines several individual functions in a single unit. The smallest are credit-card or key sized units designed for carrying in a wallet or on a keyring, but others are designed to be carried in a trouser pocket or belt-mounted pouch.[1]
History
The idea of incorporating several tools in one unit is very old, dating back at least as far as Middle Roman times.[2] Many of these were used for eating.
In 1983 Tim Leatherman sold his first "Pocket Survival Tool", [3] larger and more robust than a pocket-knife-based tool, and incorporating a set of needle-nosed pliers in a butterfly knife-style mechanism. Too large for most pockets, it came with a belt pouch.
Other multi-tools
Other multi-tool functions include a hammer,[4] LED light, lighter,[5] tape measure and an assortment of screwdriver bits.
Multifunction tools may be specialized for use in certain activities. Cyclists may carry a folding tool with screwdriver bits or wrenches to allow adjustment of bicycle fasteners during a ride, or for repairing a broken chain. For sport fishermen, a specialized multitool may combine common functions such as cutting fishing line, crimping weights, removing hooks or opening split rings. A specialized multitool may be used for adjustment, cleaning or minor repair of a firearm in field use. Since 2007, smartphones have emerged as a popular multi-tool category.
