What is a key use for diagonal pliers?

Diagonal pliers, also known as diagonal cutting pliers or wire cutters, are specifically designed for cutting wire and other materials. Their uniquely angled blades provide leverage that allows the user to cut through objects effectively, especially in tighter spaces. This feature makes diagonal pliers an essential tool for various tasks in aviation maintenance where precise cutting is often required, such as trimming wires during installations or repairs.

The primary function of these pliers is cutting, which distinguishes them from other types of pliers that serve different purposes. While they can sometimes be used in a gripping capacity, that is not their main purpose, and they lack the design elements that make other types of pliers more effective for gripping or turning. Using diagonal pliers for something like measuring is also impractical, as they do not provide the accuracy or functionality needed for that purpose.
