What tool is used to strip insulation from wire?

Wire strippers are specifically designed to remove the insulation from electrical wires with precision, allowing for clean and accurate stripping without damaging the conductive core of the wire. This tool comes in various designs, with some featuring multiple notches to accommodate different wire gauges. The primary function of wire strippers is to expose the bare wire, making it ready for connections such as soldering, crimping, or attaching to terminals.

While other tools, like voltage testers, are essential for safety checks, and screwdrivers or pliers are useful for handling connections and securing or loosening fasteners, they lack the unique design and functionality that wire strippers provide. Using the wrong tool for stripping insulation can lead to frayed wires or damage, which is why wire strippers are the preferred choice for this specific task.
