Jigsaw

A jigsaw is a type of saw used for cutting arbitrary curves, such as stenciled designs or other custom shapes, into a piece of wood or similar material. It is usually used in a more artistic fashion than other saws, which only cut in straight lines and exist mainly to chop pieces of wood to length for building structure. In this way, it is similar to the rasp and the chisel.

Traditional jigsaws are hand saws, consisting of a handle attached to a small, thin blade. More modern jigsaws are power tools, made up of a motor and a reciprocating saw blade.
