Hair is soft, steel is hard. However, in the confrontation between stubble and razor, the second soon gives up. Why this is happening, the American physicists decided to find out.

They studied the structure of the blades, illuminating them before and after using a scanning electron microscope, and also examined how exactly they interact with the hair.

It turned out that the blade is not damaged when it hits the hair at a right angle. In other cases, it gets caught between the tiny scales covering the hair, which increases the load and in those places where the steel is heterogeneous due to carbon inclusions, grooves appear.

This discovery may become a prerequisite for the development of stronger blades, writes TASS.

We will remind, earlier we told how the coronavirus is transmitted between cats.
