Human hair clippers cannot shave pets, easily hurt pet skin, and cause unnecessary harm to pets. The difference is that the blades, cutters, etc. are different.
The hardness, density, and growth direction of pet hair are different from those of humans. Therefore, the shaver and the hair clipper are different in terms of blade sharpness, blade width, blade structure, design process, and the like.
To put it simply, for example, human beards, hair, other body hair, etc., have different hardness, density, growth direction, and different skin curvature, there will be different hair removal tools, such as razors, hair clippers, and epilators. So animal shavers work the same way.
