A safety knife is a cutting tool designed to minimize the risk of injury during use. It typically features a retractable blade that automatically retracts when not in contact with the material being cut. This design helps prevent accidental cuts and makes it safer for both professional and personal use. Safety knives are commonly used in various industries, including packaging, construction, and crafting. They come in different styles, such as box cutters and utility knives, and are often equipped with ergonomic handles for better grip and control. Their primary purpose is to enhance safety while maintaining cutting efficiency.
