Jigsaw (tool)

A jigsaw is a saw which uses a reciprocating blade to cut irregular curves, such as stenciled designs, in wood, metal, or other materials. Today they are electrically powered and known as scroll saws, and have been largely displaced by portable power jigsaws.

Jigsaws first emerged in the 19th century and employed a treadle to operate the blade. The modern portable jigsaw was introduced in 1947 by Scintilla AG (later acquired by Bosch) .
