A saw is a tool for cutting wood or other material, consisting of a serrated blade (a blade with the cutting edge dentated or toothed and worked either by hand or by steam, water electric or other power. The teeth of the saw are each bent to specific angle and this angle is called "set". The set of a tooth is dependent on the kind of cut the saw will be making. .
There are many different types of saws in the toolbox of a construction worker. A construction worker chooses the type of saw depending on the purpose of making the cut. In a virtual, mental toolbox you could have many different types of saws.
This post is featuring a reciprocating saw. 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. A reciprocating saw is used in construction and demolition work.
Why would anyone want a reciprocating saw in their mental toolbox?
