What tool should be used to skin copper wire?

Using a wire stripper is the most appropriate choice for skinning copper wire. Wire strippers are specifically designed for this purpose, allowing for the safe and efficient removal of insulation from the wire without damaging the copper conductors inside. These tools have multiple notches that correspond to different wire sizes, ensuring that you can choose the correct cutting width for the gauge of wire you are working with.

Employing wire strippers minimizes the risk of nicking or cutting the wire itself, which can lead to weakened connections or short circuits. This precision is crucial in electrical work, where maintaining wire integrity is essential for safety and functionality.

While other tools like knives or side cutters could technically be used to strip insulation from wire, they are less safe and efficient compared to wire strippers. Pliers could also be used, but they do not provide the same control and specificity needed for cleanly removing insulation while preserving the wire.
