A box cutter is a simple cutting tool commonly used for opening boxes and packages. It typically features a retractable blade that can be extended or retracted for safety. Box cutters are often made of plastic or metal and are lightweight, making them easy to handle. They are widely used in warehouses, shipping centers, and homes. The blade of a box cutter is designed to be sharp and replaceable, allowing for efficient cutting of cardboard and other materials. Many box cutters also have a safety lock to prevent accidental blade exposure. They are an essential tool for anyone who frequently handles packaging materials.
