Please recommend a sharp tool for shaving your head! If you have used it, tell me which brand has the shortest shave. Don't use a knife with thick teeth, you can still feel stubble after pushing it!

If you want to shave your head and want your hair to be short, I recommend you to use a manual razor. Manual shaver can better control the depth and angle of shaver, so that you can shave your hair more accurately.

When choosing a manual razor, you need to pay attention to the sharpness and fit of the blade. Some brands of manual razors also provide blades with different thicknesses, so you can choose the blade that suits you best according to your own needs.

Some popular brands of manual razors include Gillette, Comfort (Comfort/Apache/Feather), Wo Du and so on. These brands have a good reputation and a wide range of users.

It should be noted that manual razors need to be used with caution, and the blades need to be replaced frequently to avoid infection. In addition, if you want to shave your head, it is best to shave off most of your hair with an electric razor first, and then use a manual razor for fine treatment.

In short, choosing a sharp manual razor, using it correctly and paying attention to personal hygiene habits can help you shave a smooth and tidy bald head.
