Whether the electric shaver can shave the beard clean or not is the most important factor. A well-designed cutter head can make shaving a pleasure. The blades of razors sold in the market can be roughly divided into three types: turbine type, staggered knife type and mesh type.
The turbine cutter uses a rotating multi-layer blade to shave off the beard. Blade design is the most commonly used in razors. The staggered cutter head uses the principle of staggered vibration of two metal blades to push the beard into the groove and scrape it off. The mesh cutter head is designed with dense mesh film to generate rapid vibration and scrape off tiny beard residue.
Extended data:
Whether the cutter head is sharp or not directly affects the shaving efficiency. In addition, the number of cutter heads is also a decisive factor.
The head of the early electric shaver was designed with a single head, so it was impossible to shave the beard clean. With the development of technical design, better shaving effect can be obtained.
Double-blade electric shaver has always had a good shaving effect, but it is not easy to shave off small beard residue or the curved angle of chin. In order to solve this problem, the new product has added a "third knife" design and added a third knife between the two knives. The double knife sinks into the skin, and the third knife will completely scrape off the stubble that cannot be scraped off.
