Throughout history, humans carved wood and stone to create and protect themselves. The chisel was his best ally since without it he would continue to live under a pile of stones. According to reputable sources , chisels with more than 10,000 years old have been found. And remember that the Egyptians used it to carve the pyramids and Michelangelo, to sculpt the David. As if that were not enough, it was also necessary to make fishing boats.
It is undoubtedly one of the simplest and most useful tools since for thousands of years it has been possible to engage in fishing, without the dangers of hunting or the hard work of a farm for humans. The first of these elements was made with wood by the man from Cromagnon, about 30,000 years ago.
The first ones are at least 3,000 years old. Candles became important elements of religious ceremonies during the Middle Ages, although they were also used to light streets or watch food go by. However, the candles turned out to be expensive, smelly and inefficient, so the migration to other elements was left aside. Nowadays, with the exception of electricity cuts, they are used for romantic moments, even more so if one takes into account that many of the current ones are flavored.
Perhaps there is no other element as simple as this, which aims to unite materials with each other. The first ones were made in bone about 30,000 years ago. Its first use was to make clothes and protect humans from the weather. More recently, they allowed the manufacture of sails for ships that arrived around the globe. They were even used as weapons by the ninja.
It is a machine for machining parts per revolution by removing material in the form of chips using a cutting tool. It makes manual labor a simpler task, allowing to increase production and lower costs. The lathe is considered the queen machine, since it allows the machining of a multitude of materials, and the limit, in most cases, is imposed by the skill of the operator. In fact, the lathe is the only machine tool capable of building itself. It is about 2,300 years old. In 1480, Da Vinci designed a lathe that used a pedal to get moving, something that allowed it to be in constant rotation.
It not only keeps the schedule of trains, meetings or calls in order. Since the human being was human he tried to develop devices to know the time. The sundial was probably invented more than 7,000 years ago. But since those devices did not work during the night, another one was needed to do it. It was so that the Greeks developed the water clock or clepsydra. The first consisted of a clay vessel containing water to a certain extent, with a hole in the base of a size sufficient to ensure the exit of the liquid at a certain speed and, therefore, at a fixed time. The bowl was marked with several stripes that indicated the time in the different seasons of the year. In 1656, the German mathematician Christian Huygens created the first pendulum clock, able to have an error of just one minute per day. In 1761, a British carpenter named John Harrison manufactured the first marine chronometer, capable of not desynchronizing itself with the movement of the ship. In the 19th century, the first personal watches appeared.
According to a Greek legend, the first saw was created by a boy named Perdix who, while apprenticed to his uncle, was inspired to create this tool by looking at the spine of a fish. The saw, by making it easier to cut wood or other materials, allowed humans to build everything. Using a saw is one of the skills every man should have. Beyond the legend, the ancient Egyptians used saws more than 5,000 years ago. It was not until 1777 that Samuel Miller patented the first circular saw in England. Forbes recalls that sometime in 1900 a resident of the Appalachian Mountains made music from a saw. These melodies were very popular in the United States between 1920 and 1930.
