A jig saw is an electrically powered tool used for sawing wood into various shapes. A jig saw is composed of a narrow, vertical blade that moves up and down through a reciprocating motion. Jig saws are commonly used to cut curves and intricate designs on wood and other similar materials such as plastic and metal. Most jig saws used by carpenters can be manipulated by hand, although there are some jig saws that are attached on a table. The speed of the sawing motion done by a jig saw can be controlled depending on how slow or fast does the carpenter want to craft a particular material.
