The EZ3 Self-Retracting Safety Utility Knife is a lightweight and easy to use safety cutter. To prevent painful and costly injuries, the blade springs back into the cutter once the cut is completed. With a shorter blade depth the contents of boxes are less likely to get damaged. The unique integrated hinge design and easy-open dial make for a convenient tool free blade change. Can be used with the UKH-430 Holster and CL-36 Lanyard. Spring-back retracting blade for added safety. Super easy tool free blade change. Ambidextrous three button design. Lightweight durable plastic. High-visibility yellow. Includes one SP-017 Safety Point Blade. Holds five additional blades.
