The typical style of the Reciprocating 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
