Which type of pliers are best for cutting wire?

Diagonal cutting pliers are specifically designed for cutting wire and other materials. Their sharp, angled cutting edges allow for a clean cut without the need for excessive force, making them ideal for tasks that involve electrical wiring or thin metal. The design of diagonal cutting pliers provides a leverage advantage that increases efficiency and effectiveness when cutting through tougher materials.

In contrast, needle-nose pliers are primarily used for gripping and manipulating small objects in tight spaces, rather than cutting. Slip-joint pliers are adjustable and primarily used for gripping and turning nuts and bolts, making them unsuitable for cutting tasks. Locking pliers are designed to hold objects tightly in place and are not intended for cutting; they can also damage materials if used improperly for cutting functions. Therefore, diagonal cutting pliers are the appropriate choice for cutting wire due to their specialized design and functionality.
