Which tool is commonly used by linemen for cutting wires?

Wire cutters are specifically designed for cutting wires and are a fundamental tool in a lineman's toolkit. They feature sharp blades that can cleanly slice through copper or aluminum wires of varying gauges without fraying or damaging them. This precision is crucial for linemen, who often work with electrical systems where clean cuts are necessary to ensure proper connections and reduce the risk of electrical shorts.

Screwdrivers are primarily used for turning screws and do not have cutting capabilities. Pliers can grip and bend wires but are not optimal for cutting, as they can crush or deform the wire instead of providing a clean cut. A hacksaw is a cutting tool that can cut through metal but is not practical for the precise and quick work typically required for wire cutting in electrical applications. Therefore, wire cutters are the most suitable and efficient tool for this task.
