Combination pliers are so called because they enable the user to do a ‘combination’ of jobs, as their jaws can both cut and grip. Some combination pliers have other additions, especially if they’re designed for use in particular industries or for specific tasks.
The handles of combination pliers will usually have a plastic coating, for added comfort and grip. The size and length of the handles will depend on the size of the pliers, as well their intended uses. For example, high leverage pliers have longer handles than most standard pliers. Pliers designed for use by electricians and linemen have insulated handles, often tested and approved by VDE, an internationally accredited institution in the field of testing and certification of electrical engineering devices.
Jaws
The jaws of combination pliers open and close along with the handles. They have flat edges for general gripping, which are often serrated for extra grip, although sometimes they are smooth. They usually have squared tips.
Cutters
The cutters built into the jaws of combination pliers are usually designed to cut cables and wire, rather than sheet material. Their position, near the pivot point, gives them maximum leverage.
Pipe grip
The pipe grip is a rounded, serrated, cut-out in the jaws. It is primarily used for gripping rounded stock, like pipes and cables. The shape should reduce the chance of crushing the stock, the way the flat edges could. Most combination pliers have a pipe grip, but not all of them.
Pivot point
The pivot point is a kind of hinge that allows the handles and tips to open and close so the jaws can grip or cut, and then be opened again.
