Why ‘that’ shape in the middle of the blade! Know the revolutionary invention of ‘King Gillette’ 100 years ago!

All of us must have seen shaving blades at one point or another. There are different brands of blades available in the market, but have you ever looked closely” And the masterstroke of science is hidden.

King Camp Gillette’s revolutionary invention

It started in 1901, when King Camp Gillette of America along with his colleague William Nickerson invented the first ‘safety razor’ and thin blade. In those days, men used to shave with razors, which carried the risk of cutting the cheeks. Gillette recognized this danger and created the razor.

Razors patented by the Gillette Company at the time had three screws or small balls to fasten the blade to the top of the razor. In order for the blade to lock perfectly into the razor, a similarly sized cut was made in the center of the blade.

Entry of other firms and Gillette’s monopoly

Gillette’s design was hugely popular. Initially, Gillette protected its design patents for 25 years. But when this patent ran out, other companies started making blades.

Now the other companies had a big problem. At that time, only ‘Gillette’ razors were sold in the market. If new companies had made blades of a different design, they would not have fit into Gillette’s razors. So customers would not have bought their blades. To avoid this commercial loss, all companies decided to copy Gillette’s own design and put the same cut in their blades that would fit the razor. Later this design became the global standard.

The reason behind the design – flexibility

This shape in the center of the blade not only has history, but also an important scientific advantage.

Controlling pressure: The blade is made of very thin and sharp metal. If it’s laid perfectly flat, the slightest pressure on it while shaving will snap it right in the middle.

Increasing flexibility: This particular cut in the middle gives the blade great flexibility. When we tighten the razor screw, the blade is slightly bent, but not broken. This shape distributes the stress on the blade equally on all sides.

Although there are new shaving technologies and trimmers on the market today, this old blade design is still used around the world. This is a perfect example of how business acumen and science can be perfectly combined at the same time.
