A reciprocating saw is a type of saw in which the cutting action is achieved through a push and pull reciprocating motion of the blade.
The term reciprocating saw is commonly assigned to a type of saw used in construction and demolition work.
This type of saw, also known as a recipro saw, Sabre Saw, or Sawzall (a trademark of the Milwaukee Electric Tool Company) has a large blade resembling that of a Jigsaw and a handle oriented to allow the saw to be used comfortably on vertical surfaces.________
The typical style of this saw has a foot at the base of the blade, also similar to a jigsaw.
Designs range widely in power, speed, and features, from less powerful portable, handheld models that are usually shaped like a cordless drill, to high-power, high-speed, corded models. Modern reciprocating saws almost all have variable speed, either through trigger sensitivity or through a dial.
Another feature that has become important to the way these saws are used is the inclusion of an orbital action.
The action consists of oscillating the traversed reciprocation in up and down fashion (perpendicular to the motion of cut) causing the tip of the blade to move in an oval pattern, up and down as well as back and forth.
