Pliers and Nippers Pliers are often considered a general-purpose tool and are often used for purposes for which they were not designed. Pliers are meant for gripping and cutting operations. They are not recommended as a substitute for wrenches because their jaws are flexible and frequently slip and do not hold the work securely. The handle of electricians' pliers should be insulated. In addition, users should wear electricians' gloves.
Nippers sometimes cause injuries when they are used to cut short ends of wire.
Vises Vises are used for holding material while it is being worked. Material can be securely clamped in the jaws of a vise and held while the work is performed. The handle used to tighten the jaws of the vise should not be struck with a hammer to gain additional holding strength. Tighten with hands only. Saws Saws should be properly selected for the job.
