A paper cutter is a tool used to cut large stacks of paper quickly and accurately. It typically features a sharp blade that slides down a guide, allowing users to make straight cuts. Paper cutters are commonly used in offices, schools, and print shops for tasks like trimming documents, photos, and other paper materials. There are various types of paper cutters, including guillotine cutters, rotary cutters, and stack cutters. Each type serves different purposes and offers unique features. Safety is an important consideration, as many paper cutters come with protective guards to prevent accidental injuries while cutting.
