In order to know the meaning of the term hammer, we are going to proceed, first of all, to discover its etymological origin. Specifically, it emanates from Latin, more precisely from the word "martellus", which can be translated as "hoe", "hammer" or even "axe".
Hammer is a term that refers to a tool that has a handle and a head and is used for striking.
Usually the handle of the hammer is made of wood , while the head is usually made of iron . The user must take the hammer by the handle with one hand and hit with the head what he wants to nail, embed or sink.
With the blows of the hammer, it is possible to move a piece. Typically, this instrument is used to force a nail into a surface: the force of the blows on the nail allows its tip to penetrate the material.
Given this use, hammers often have an open wedge in the rear section so that it is possible to pull out the nails with it. Thus, the hammer is used to nail and unnail .
The hammer can also be used for breaking. If, for example, a glass window is violently hit with a hammer, the glass bursts. That is why there are usually hammers on public transport, so that an opening can be created to exit the unit in case of emergency.
In addition to all the above, we cannot ignore that there are different types of hammer. Exactly among the most used, some such as the following must be highlighted:
-The ball hammer, which is identified because it has one flat end while the other has a semisphere. It is mainly used in sectors such as plumbing, forging, metal carpentry or locksmithing.
-The traditional carpenter's hammer, which has a wedge on one end of the head and a square shape on the other.
-The sheet metal hammer, which has two flat ends and large dimensions in order to be able to work the sheet metal well.
-The claw hammer, which has at one end a kind of nails that are used for leverage and at the other a head similar, although somewhat smaller, to that of a carpenter's hammer. This tool is widely used by both formworkers and carpenters.
In the same way, we cannot ignore that the god of Norse mythology Thor, the god of thunder and strength, is identified by carrying a hammer. This one, which has a short handle, is called Mjolnir, never misses its target and was created by two dwarves.
Hammer, on the other hand, is the name of a small bone found in the middle ear of humans and other mammals. The hammer is located between the incus and the eardrum .
In the field of sport , finally, the hammer is an object that is thrown in an athletics event . The hammer throw consists of throwing a metal ball linked by a cable to a handle: the athlete who manages to send the hammer the furthest is the winner.
