Heavy-duty stationery knife with a snap-off blade

Description

A utility knife is a staple for both office workers and homemakers for household use. It cuts through paper, cardboard, and other materials with ease, producing a clean, even cut. The knife consists of a plastic handle, a metal blade, and a lock. The blade is multi-sectioned, with sections that snap off when the blade loses its sharpness. The plastic lock securely holds the blade in place.
