This compact cutter with ceramic blade is perfect for cutting cardboard boxes. It can also be used for individual sheets of paper or as a letter opener. The blade is made by Kyocera, which is known for its high-quality ceramic blades. Unlike metal, ceramic is both more durable and rustproof. The robust body made of fiberglass protects both the blade and your fingers when closed. When fully opened, its semicircular shape lies comfortably in the hand. The back is magnetic and can be attached to a desk, refrigerator or other metal surfaces for easy storage.
