Razors are tools designed for shaving hair from the skin, commonly used for personal grooming. They come in various types, including manual razors with blades and electric razors that use a motor to cut hair. Manual razors often have a handle and a replaceable blade, while electric razors can be corded or cordless, providing convenience and speed. The history of razors dates back thousands of years, with early versions made from materials like flint and bronze. Today, many people use razors for facial hair removal, body grooming, and maintaining a clean appearance. Safety razors and disposable razors are popular choices for everyday use.
