It is said that mankind had begun to use something similar to a blade in order to remove beard, hair, hair, and hair long before a long history.In the Paleolithic period, the shells, animal bones, shark teeth, and flammable stones were processed into cutting tools.In the Stone Age, people were forced to shave their beard as a means of self-defense so that they could not hold a beard in battle.It is said that the competition for survival is the origin of the ruin of the cimosol.

In ancient Babylonia, the promise of a person with no beard is said to be a good reason, and in the contrary, it is known that in Egypt he shaved the beard and head of the chin.It is said that the face with no beard was shown to indicate the height of the social status.It seems that the devil who had settled in his body at the time of his time had fled his head from his head to heaven, and he had shaved his hair and his jigs.There was a king who had shaved her beard, and wearing a gold or silver imitation of a "beard."
This custom also spread among the Greeks and Romans in 330 BC, under the reign of Alexander the Great, as a defensive measure to prevent the enemy from holding their hair in the battle against white soldiers.Thus, as the shaving custom gradually penetrated into most parts of the world, tribal men who were not in the habit of shaving their hair came to be called "Barbarian" (Barbarian) in the sense of unshaved human beings (unbarberd).
With the discovery of the bronze ware, various forms of knives came to be made.

The folding-edge reza, which began to be used in Rome, spread to the general public, but the practice of shaving every day is considered to be the Scypio, who was a Roman statesman. In ancient Greece, there is a record that a three-day-moon-shaped casmith had been found in 325 years.
