The hammer is a very common tool in the woodworking creation process. Usually, the hammer we see is composed of two parts: the hammer head and the handle. Its main function is to make it change shape or shift by beating. Generally speaking, it is used to correct objects or knock objects.
▲ Did the hammer originate in primitive society?
The working people in the primitive society smashed a nut with a stone, or hit a stone with a stone to generate a spark, so can this stone be called a hammer?
▲ The hammer starts from the wisdom of working people in primitive society. However, the previous name of the hammer was not hammer, but "melon" or "guduo", because the head of the hammer resembled a melon or a ball of thorns. People in ancient times used hammers as weapons. Because of the different shapes of the hammer heads, they were divided into two types: standing melons and lying melons.
▲Hammers also have different lengths. Long hammers are about two meters long, short hammers are only a dozen centimeters, and most standard styles are between 50 centimeters and 70 centimeters. Now usually divided according to our daily functions, hammers can be divided into claw hammers, octagonal hammers, nail hammers, teat hammers, inspection hammers, etc.
The claw hammer is the most used in our daily life. According to legend, it was invented in ancient Rome. The modern claw hammer was improved by the Germans. As the name suggests, the name of the claw hammer is because one end of the hammer has a V-shaped opening, like Goat horns, hence the name. The function of the claw hammer is that one end can knock nails, and the other end can pick up nails. One hammer can be used for both purposes. The V-shaped opening is used to pick up nails. It is a kind of labor-saving lever.
▲ Claw hammers are generally divided into four types according to the material of the hammer: iron hammer, copper hammer, wooden hammer and rubber hammer.
▲ Hammer Among them, the hammer is more common and is generally used to drive nails into wood to play a fixed role.
▲Copper hammer Copper hammer is softer than iron hammer, it is not easy to leave hammer marks on objects, and copper hammer has a good advantage that copper hammer is not easy to spark, and it is not easy to produce sparks in some flammable and explosive places. Copper hammers can come in handy for occasions.
▲Judge Hammer Every judge has a wooden hammer, which is equivalent to the gavel in the past. We also have a wooden hammer in our carpenter's box. It is mainly used for knocking chisels, and it can also be used for imposition. Wooden hammer Compared with the hammer, the advantage is that the strength is easier to control, and the marks after the hammer drop are very shallow, which saves effort. Generally, large wooden hammers are made of cork, which is relatively light, while small wooden hammers are made of hardwood.
▲Rubber hammer The rubber hammer is more elastic and can play a good buffering role. We mainly use it for light beating, so that the connection between wood and wood is more delicate and close.
