   A rotary reciprocating saw is a type of saw that spins a cutting implement around a rotary axis, instead of thrusting it along a linear axis. The first use of such devices was in medicine , where cutting through bone warranted the need for a saw with minimal stroke length, and a cutting action that could be implemented through depth cut rather ...

8. Quick return mechanism - Wikipedia

   en.wikipedia.org/wiki/Quick_return_mechanism

   A quick return mechanism is an apparatus to produce a reciprocating motion in which the time taken for travel in return stroke is less than in the forward stroke. It is driven by a circular motion source (typically a motor of some sort) and uses a system of links with three turning pairs and a sliding pair.
