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 different types of paper cutters, including guillotine cutters, rotary cutters, and trimmer cutters. Each type has its own mechanism and is suited for specific cutting needs. Safety features, such as blade guards, are often included to prevent accidents during use.
