Combination Pliers usually have serrated jaws, which provide friction when gripping, and square tips, although there are some variations in jaw design. Combination pliers often have a rounded, serrated cut-out in the jaws, called a pipe grip, for holding rounded materials Combination pliers are referred to as lineman s pliers. However, lineman's pliers are specialist combination pliers; made for heavy-duty work and with specially insulated handles, for safety around live electrics. This is because a lineman works with power lines or communication cables. The gripping jaws of pliers are designed to produce a more forceful grip than just using your hands. The design and size of the jaws determine what they can grip and where they can reach. Combination pliers come in various sizes with differences in jaw shape. The cutters of combination pliers, sometimes called side cutters, are positioned near the pivot point, this is the position in the jaws where the most force is exerted. These cutters are usually designed to cut cables and soft wires. They use leverage to amplify (increase) the pressure exerted by the user when they squeeze the handles together, so that the force between the jaws is greater than the user's input pressure. They can be used, for instance, to tighten a ferrule (a clamping collar used to fix parts together) or close chain links, such as those used to make jewellery or chainmail Applications include the straightening or twisting of wires.The firm grip provided by pliers means you can pull objects, usually to remove them from something. Pliers are often used to extract things like staples or thin nails. Length X Width X Height (cm) : 19X6X3 & Weight (kg) : 0.27
