Cut up to 10 sheets at a time. Trimmers feature a hardened steel, zinc plated blade which uses a scissorin action to quickly and easily cut through paper. The board includes both ruled inch and metric scales and a permanently printed grid pattern to ensure accurate cutting. The handle features a molded grip designed for comfort and safety. A safety rod is included to help keep fingers away from the cutting blade, and the trimmer has a built-in safety lock which holds the blade securely in the down position when not in use.
