How was the razor invented?

Gillette razors are now a famous brand. In fact, the razor was invented by Gillette in the United States.

One day in 1895, Gillette walked into a barber shop. Everyone is talking about how they are afraid of shaving and how they often bleed when they are shaved. "It would be great if there was a safety razor." The barber's unintentional remark made Gillette realize that if he invented a new type of safety razor, there would definitely be a market. After returning home, Geely concentrated on experiments. After sharpening the blade, he first tried it on his own face, and then on the faces of his brothers and friends. Everyone's faces were left with bare chins full of incisions. However, more than a year later, the experimental results are still not satisfactory. With the encouragement and help of the famous inventor Nicolson, Gillette finally made a "T" shaped razor. The blade of this kind of razor is very thin and sharp, but when shaving, it can change the angle with the contact surface, so it will not hurt people. In 1901, Gillette applied for a patent for his own safety razor and founded the world's first company to sell such razors.
