What is a razor?
Tools for shaving. It is a self-service tool and is 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 it is not used for a long time, the battery must be taken out to avoid damage to the internal parts due to battery leakage. It consists of a blade and a hoe-shaped tool holder. The knife holder is made of aluminum, stainless steel, copper or plastic; the blade is made of stainless steel and carbon steel. For sharpness and durability, the cutting edge is mostly treated with metal or chemical coating. When in use, install the blade on the blade holder and hold the handle of the blade holder for shaving. There are two types of safety razors, one is a double-edged blade mounted on the blade holder; the other is two single-edged blades mounted 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.
