The heavy-duty Fully-Automatic Self-Retracting Safety Knife has a spring-loaded blade that “clicks” into place as it meets the materials being cut. This action ensures the blade automatically retracts the instant it loses contact with the surface. The retraction occurs even when the blade slider is engaged and cannot be manually overridden. Use this knife for enhanced protection against injuries in the workplace. This knife is ideal for cutting corrugated, packaging, film, trimmings, shrink wrap and strapping. For right- and left-handed users.

Replacement blades also available.
