Abstract
A safety knife comprises a main body formed with a slot having a narrow open mouth, into which the material to be cut is inserted, and a blade mounted on the main body with a portion of its cutting edge extending across the slot at a location spaced inwardly from the mouth of the slot. The blade is mounted in a recess in the main body for sliding movement across the slot, against the action of a spring, and is coupled to a sleeve which is slidable on the main body. The user holds the knife by the sleeve so that, as the knife is used to cut material, the relative movement between the sleeve and main body causes to blade to slide across the slot, thus enhancing the cutting action.
