American inventor King Gillette patented a razor with blades that could be easily changed in November 1904. At that time, Gillette was almost 50 years old, and he thought about the possibility of creating such a razor for 10 years.
It all started with the fact that Gillette's razor was dull. In order to put it in order, it was necessary to take it to the grinder, spend time and money. At that moment, King thought it would be nice to have a razor with replaceable blades.
He quickly figured out what this razor should look like. The blade is attached to the T-handle with clamps. In a matter of seconds, the old blade can be easily replaced with a new one. But the main problem was different - where to get steel that would be strong and thin? And, most importantly, cheap, so that the cost of such a razor does not exceed the fee for the services of a grinder.
The engineer William Nickerson was able to prepare the necessary steel, and King Gillette had only to find investors willing to invest in a promising, albeit risky, project. He solved this problem. True, buyers did not immediately appreciate such a useful invention: in the first year, only a few dozen machine tools and replaceable blades were sold.
But even here Gillette found a way out - he began to sell machines at a price much lower than the amount that was spent on making them. However, after a while customers had to buy new blades, otherwise, the machine was simply useless. It was on the blades that the enterprising King Gillette made money.
Soon Gillette became known throughout America, his products were in demand, bringing the inventor a good income. He was familiar with the top officials of the country, and even jokingly suggested that Theodore Roosevelt, who had ended his presidential term, become the head of one of his branches in Arizona. True, Roosevelt was not at a loss and said that he did not trust the man who made razors, but he himself wears a mustache.
The First World War brought King Gillette millions of dollars; in 1917 alone, 36 million blades were purchased by the American army. And during the war years, soldiers got used to using razors, buying them in peacetime.
At the end of his life, Gillette, who died in 1932, proudly declared that his invention was being used from the north of Norway to the Sahara Desert.
Many believe that Gillette razors appeared in our country only during perestroika. This is a delusion, one of the company's factories was opened in tsarist Russia.
