An electric razor is a razor with a rotating or oscillating blade. Electric razors generally do not require the use of shaving cream, soap, or water. A razor is a razor used to remove body hair throughout the shaving process. Types of razor blades include straight razors, safety razors, disposable razors, and electric razors. Two haircut parts: a thin, perforated blade and a "scissor", a group of small blades that move very quickly under the blade. The small holes drilled in the blade are smooth on the outside, but sharp on the inside, and act like a second blade.
