Heavy-Duty Self-Retracting Safety Utility Knife.

The Superior Steel UK755 Heavy-Duty Self-Retracting Safety Utility Knife is built for general-purpose cutting tasks where added blade control and user safety matter. Constructed with a heavy-duty zinc-alloy body, anti-slip TPR grip, and SK5 high-carbon steel blade, it delivers the strength and cutting performance needed for office, home, workshop, warehouse, and DIY applications. Its self-retracting blade design extends on push and safely retracts upon release, helping reduce blade exposure during repeated cutting tasks. A slide-out sleeve allows fast, tool-free blade replacement in seconds, while the integrated storage compartment keeps 3 extra blades close at hand for added convenience. Finished with a comfortable grip and lanyard hole, this knife is designed for secure handling and easy access throughout the workday.
