Common uses of a side cutter are to cut wire and to substitute for a set of pliers. Side cutters are also known as lineman's pliers. Most professional electricians own a set, but they are also staple items in many non-electrician tool boxes.
A side cutter is a dual tool. Not only does it cut wire, but it can also be used as pliers to loosen stuck bolts or other tools during a project. Side cutter pliers effortlessly cut wire and help speed up the overall job. This is because the worker doesn't need to put one tool down and pick up another one to cut the wire.
