ABSTRACT:
A locking safety utility knife includes a body and an operating lever that is squeezed to deploy a retractable cutting blade from within the body. The blade can be locked in its retracted position by means of a ratchet-like mechanism including a pawl which is released by manipulating a cam operator. The pawl engages teeth formed on the outside of a door which closes the rear of a compartment formed in the operating handle to house spare blades, or a blade cartridge.
