LOCKING SAFETY UTILITY KNIFE

摘要

A locking safety utility knife includes a body (10) and an operating lever (20) that is squeezed to deploy a retractable cutting blade (12) from within the body. The blade can be locked in its retracted position by a ratcheting mechanism including a pawl (38) which is released by manipulating a cam operator (44). The pawl engages teeth formed on the outside of a door (26) which closes the rear of a compartment formed in the operating handle to house spare blades, or a blade cartridge.
