A safety razor is a shaving tool designed to provide a close shave while minimizing the risk of cuts and nicks. It features a protective guard that helps to keep the blade at a safe angle against the skin. Typically made of metal, safety razors use replaceable blades, making them both economical and environmentally friendly compared to disposable razors. The design of the safety razor dates back to the early 20th century, with the first modern version patented by King Camp Gillette. This innovation revolutionized personal grooming, allowing for a smoother and safer shaving experience. Today, safety razors are popular among shaving enthusiasts and those seeking a more sustainable alternative to traditional razors.
