Everything You Need to Know About Razor Blades

Razor blades are small, flat pieces of metal with a very sharp edge that are used for shaving. They are typically placed on a razor, a tool designed to remove body hair. There are several types of razors, including straight razors, safety razors, disposable razors and cartridge razors. The first safety razor was invented by Gillette in 1880 and was considered an important innovation in the history of razor development.

It featured a protector that rested between the blade and the skin to reduce possible injuries, making it popular among beginners and women. Safety razors are usually made of metal and can be used for a long time. All you have to do is change the blades, which are economical and easy to clean. Razor blades have been around since prehistoric times, with clam shells, shark teeth and sharp flint being used as shaving utensils. Solid gold and copper knives were found in Egyptian tombs from the fourth millennium BC.

According to the Roman historian Livio, the knife was introduced to Rome in the 6th century BC. Razor blades are made from martensitic steels, some of the strongest materials known to mankind. Martensitic steel is a superhard, heat-polished and tempered alloy used in commercial razors, surgical instruments, ball bearings and bicycle disc brakes. However, despite its strength, the blades become fatigued quite quickly after several shaves. In the early 20th century, King Camp Gillette combined the hoe shape with the replaceable double-edged blade. Even though it filed its patents in 1901, Gillette was unable to market its disposable blades until 1903. The modern razor consists of a specially designed blade mounted in a metal or plastic housing that is attached to a handle. Cartridge heads typically have several razor blades placed in them, usually between two and five blades.

They use a razor system in which many tiny blades oscillate at super-high speeds to easily cut facial hair even when it's not wet. Cartridge razors work best for men with thick skin because they are not easily irritated by blade friction caused by the numerous blades on the cartridge head.
