There are up to 20 different types of pliers in the market. In this post we will review the most common pliers . All of them have in common the composition or parts of the pliers , formed by the head, with the jaws or clamps, the area of articulation and the handle.
The pliers are the most common model and possibly have in your toolbox. You can use them to tighten and loosen mechanical joints, to stretch and bend pieces and to cut or strip wires and cables.

Unlike the universal ones, the cutting pliers do not have the clamping function. They are generally used to cut and strip electric cables. They are not to be confused with the tongs, which serve to hold an object tightly.
The flat pliers are also known as nose pliers or stork. They are characterized by having the tweezers more elongated than the universal pliers and flat. They serve to hold small pieces or to reach corners of difficult access and they are often used to manipulate cables and wires, but unlike the previous two, flat-nose pliers do not carry the cutting function.
The adjustable pliers have a mobile screw in the movable joint that serves to adjust the maximum opening of the jaws. In this way, they allow handling pieces of different sizes without having to have several pliers.
Within the adjustable pliers, we find the extendable pliers that move the joint in various positions. They are used to tighten large screws or to hold pieces of irregular shapes. They are often used in plumbing jobs and are also known as parrot beak pliers.
Another type of adjustable pliers are the planer pliers, which instead of several opening positions have only two positions.
