Razor

A razor is an appliance for shaving the beard.It is a self-service tool, mostly used by adult men. Shavers can be divided into three categories: safety shavers, electric shavers, and mechanical shavers according to their structure.

In order to ensure the shaving effect, it is best to choose high-performance alkaline batteries for dry electric shavers. If the battery is left unused for a long time, the battery must be taken out to avoid damage to internal components due to battery leakage.

Safety razor: It consists of a blade and a hoe-shaped knife holder. The knife holder is made of aluminum, stainless steel, copper or plastic, etc.; the blade is made of stainless steel, carbon steel, in order to be sharp and durable, the cutting edge is usually treated with metal or chemical coating. When in use, the blade is installed on the knife holder, and the handle of the knife holder can be shaving. There are two types of safety razors, one is to install a double-edged blade on the blade holder; the other is to install two single-edged blades on the blade holder. When shaving with the former razor, the user needs to adjust the contact angle between the blade edge and the beard to ensure the shaving effect.

The latter kind of knife holder has a longer handle, and the blades are installed on the knife holder in parallel in two layers. When shaving, the head of the blade holder can rotate with the face shape on the pivot on the upper part of the blade holder, so that the blade edge maintains a good shaving angle; and, after the front blade pulls out the root of the beard, it is immediately The rear blade is cut from the root. Using this razor to shave your beard is cleaner and more comfortable than the previous one.

Electric shaver: The electric shaver is composed of a stainless steel mesh cover, an inner blade, a micro motor and a shell. The net cover is the fixed outer blade with many holes on it, and the beard can extend into the holes. The micro-motor is driven by electric energy to drive the inner blade to move, and the beard extending into the hole is cut by the shearing principle. According to the action characteristics of the inner blade, electric shavers can be divided into two types: rotary and reciprocating. The power sources used are dry batteries, accumulators, and AC charging.

Mechanical razor: Use the mechanical energy storage mechanism to drive the blade to shave the beard. There are two types. One is equipped with a rotator inside, which uses the energy storage of the spring to make the rotator rotate at a high speed when the spring is released to drive the blade to shave; the other is equipped with a gyroscope inside with a pull wire wrapped around it to pull Pull the wire and the gyroscope will drive the blade to shave.
