What is one of the key features of a jigsaw or sabre saw?

One of the key features of a jigsaw or sabre saw is that it operates with a reciprocating blade. This design allows the blade to move up and down in a linear motion, making it excellent for cutting through various materials, including wood, plastic, and more. The reciprocating action enables the saw to make intricate cuts and curves, providing versatility that is especially advantageous in projects requiring detailed work.

In contrast to tools that are limited to straight cuts or that are solely manual, the jigsaw's mechanical design allows for a wider range of cutting capabilities. This includes not just straight cuts but also complex shapes and tight corners, which is critical for many artistic and functional applications in woodworking and construction. Additionally, while jigsaws can be used for cutting metal with the right blade, their primary usage is in softer materials, emphasizing the importance of proper tool selection based on the material being worked with.
