A jigsaw power tool is a jigsaw made up of an electric motor and a reciprocating saw blade. A jigsaw with a bevel function on the sole plate allows cutting angles of typically up to 45 degrees relative to the normal vertical stroke for cutting miter joints. In the past, what are now usually called scroll saws were often referred to as jigsaws. A power jigsaw may also be referred to, by some manufacturers, as a "bayonet saw" or sabre saw. ==History== In 1946 Albert Kaufmann, an engineer of Scintilla AG company in Solothurn, Switzerland, replaced the needle on his wife's sewing machine with a saw blade.〔(Bosch Media Service )〕〔(Invention of the Jigsaw )〕 In 1947, after development of Kaufmann's invention, Scintilla started producing jigsaws under name "Lesto jigsaw". In 1954 Scintilla was acquired by Bosch and in 1964 the name "Lesto" was replaced with Bosch. In 1966 Bosch added the pendulum action to the blade movement and in 1989 it added the tool-less blade replacement device. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Jigsaw (power tool)」の詳細全文を読む スポンサード リンク
