A razor is a tool used for shaving hair from the skin, primarily on the face and body. It typically consists of a handle and a sharp blade, which can be either disposable or replaceable. Razors come in various types, including straight razors, safety razors, and cartridge razors, each designed for different shaving preferences and techniques. The use of razors dates back thousands of years, with early versions made from materials like flint and bronze. Today, many people use razors as part of their grooming routine, often in conjunction with shaving cream or gel to ensure a smooth shave and reduce irritation.
