Which tool is designed to cut through materials using a push-and-pull motion?

The reciprocating saw is specifically designed for cutting through a variety of materials using a push-and-pull motion. This tool features a straight blade that moves back and forth rapidly, allowing it to cut through wood, metal, and plastic effectively. Its design is particularly advantageous for demolition work and in situations where maneuverability and access to tight spaces are crucial.

The ability to control the speed and direction of the blade’s movement enhances the tool's versatility, making it suitable for various applications, including rough cuts and precise trimming. Additionally, the reciprocating saw allows for the use of different blade types, adapting to the specific material being cut. This contrasts with other saws mentioned in the choices, which function differently or are not primarily utilized in a push-and-pull motion.
