More than 2,000 years to complete Reza.
It is said that the folding-blade double-edged kamisoli and the laser (Western Camisoli) came to be used from Rome in the 6th century.
In Europe, iron production began to be produced in the Alps in 658 BCE, but it was completed in the first nine centuries after the iron leaser was able to overcome the operational machinery and its ripse. It is a calculation that took over 2,000 years to complete the original form of the lone and the completion of the Reza.
To make a sharp edge, such as a lather or a knife, you need a good iron, a good fuel, a good fuel, a water (power) to be trained, and you need to make a blade of a blade from both sides by cutting it from the sides of the blades.To do so, it is necessary to change the flow of water to power, and the machine tools are needed, but until the 19th century, when they were put into practical use, they were unable to produce sharp knives such as the lazor.
In Europe, a lather was created in the regions such as Chure, France, and Zoringen, Germany, which meet these conditions for making a cutting tool, and became a world-famous production area.
T-type safety kamisoli
In 1762, a man named Jean Jacques Pérée, who used to be the mainstream of the Kamisoli, was created by a man named Jean Jacques Pérée, who operated a knife dealer in Paris, France, in 1762.When he shaved his beard at the leaser, he had a scratch on his face and had many skin diseases, so he applied the principles of Canna to guard a flat blade with a piece of wood and a slight peek at the edge of the blade. The risk of cutting off the skin was less dangerous because it was difficult to process a piece of wood guard, but it did not spread to the general public.
In 1847, in London, in London, a man named William S. Henson invented and patented a ` T-type ` Camesoli, which is similar to the current safety caromyry style, with a bladed blade with a blend of a razor at right angles to the handle. However, this'T-type ' Kamisori had to be removed from the blade because the blade was still too expensive and the blade was still not used.In addition, it took a lot of techniques to grind, so I had to go all the way to a barber's barber shop or a knife shop.
The man who made the spread of the world's popularyman.
It was in 1904 (Meiji 37) that the original form of a new blade-type safety kamisoli appeared.
The King of America was created by King C. Gillette.He devised the safety casioli, which was close to double-edged safety, with a sharp blade on both sides of the thin plate, holding it with a holder, and a handle in the middle of the anchorable plate. Gillette made a quick look at the book, but it is said that it was necessary for the time to be put into practical use and the technical completion of the book until nearly ten years of time. In particular, there were many problems that must be solved, such as how to make a low-cost blade from a thin sheet of steel, a blade and holder dimension, and how to adjust it.
William Nickerson, a professor at the Massachusetts Institute of Technology who developed the elevator push button system, offers cooperation to C. Gillette.They set up a company called the American Safety Leather in Boston in 1901, and decided the appropriate size, shape, thickness and shape of the blade, to complete the process of burning steel plates into thin sheets of steel, and to create a technical basis for the current safety casinoles.In addition, a basic patent was granted in 1904 (Meiji 37), and two-edged safety Camisoli was released three years after the invention of the invention of the Kamisoli blade and holder-holder control.
However, in the United States at that time, kamisori was not popular because it had a preconcilient view that it had to be strong and long-held.The rapid spread of Gillette's safety kamisoli is due to the first World War I.The United States government ordered 3.5 million copies of Gillette's safety Camissoli, and 36 million exchange blades as military supplies, and transported them to various places around the world together with American soldiers.
It was stimulated by the safety of this gillette, and around 1918, around 340 species of safety and kamisoli were made in the world.
