With etymological roots in the language Arabic, the term pliers is used to name a tool that allows to take, grab, mold or cut different elements. This pincers it has two arms so that the person can manipulate it (opening and closing it); from the other end ends in a point.
For example: "I'm going to find a pliers to wind the wire", “I need a pliers to hold the cable while I work”, "Juan removed the nails with the help of a pliers".
There are different types of pliers. He stork pliers , also called pointed pliers or tip clamp , is used to cut, fold and hold. These pliers allow jobs with wires and cables and, thanks to its tip, they can enter small cavities where the fingers, for reasons of size, cannot enter.
A pressure pliers or clamp Pressure On the other hand, it serves to immobilize a piece. In this way, the task of removing something or twisting it is simplified. These pliers, which in certain parts of the American continent are also known as lonely man or tweezers bitches, do not have the typical design of the tweezers, which have two equal handles.
In one of them is a bolt, with which it is possible to establish the separation distance we want for the jaws. The other is usually a lever , which serves to press on the two handles and get the tool to disengage. Having the jaws closed, you should set a size smaller than the one you want to hold, and for this it is necessary to turn the bolt, which in some models have slots to manipulate it with a screwdriver or a hexagonal wrench, with the aim to increase grip pressure.
The cutting pliers They combine pressure and cutting edge to precisely cut objects of different characteristics. In this case, the cable or the wire that you want to cut between the pliers and then press with the handles.
Cutting a cable with a plier is a task of relative simplicity; however, peeling it is much more complicated, since it requires a higher level of precision, to avoid an unwanted cut. In this case, it is necessary to control the force we print on the handles of the pliers, so that the edge affects only the protective mesh of the cable, and not the copper wires that are underneath it.
Given the shape of most pliers used for this purpose, it is not possible to make a cut along the entire perimeter of the cable with a single attempt, since the blades are not circular, but straight; For this reason, it is recommended to turn the cable and apply a little pressure at each step, until the mesh is separated into two parts. Only then is it appropriate to start pulling the end we want to peel.
The nail pliers they work in a similar way, although their shape is adapted to allow the cutting of the nails. The person you must place the nail between the tool pliers and then press. The edge of the tongs, which are usually made of steel, will enable the operation.
There are many people who do not recommend the use of pliers to cut their nails, since they point out different disorders that they can cause in the fingers; Needless to say, these are not serious consequences, but rather alterations in the shape of the nails that may be unsightly. Therefore, they prefer scissors specially designed for this purpose, which are much less aggressive and allow greater control, to achieve different finishes.
