Distinctively designed for opening cartons, Stanley 5-5/8" Self-Retracting Safe Utility Knife delivers optimized safe performance and improved safety. The spring-loaded blade system automatically retracts when slide button pressure is released. This design helps to ensure that the blade is only exposed during the actual cutting operation. Patented interlocking nose secures the blade safely between the housing of the knife. The exterior orange color was implemented as a safety feature to ensure enhanced visibility of the knife at all times. Utility knife includes one round-point utility knife blade.
