Extra Protection Safety Knife

The SK-8 Fully-Automatic Self-Retracting Safety Knife offers a unique safety feature to protect users.

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.

The Fully-Automated Self-Retracting Safety Knife features an anti-slip, cushion grip handle with a large blade slide for easy use. The stainless-steel blade channel tightly secures the blade and the metal-reinforced tip adds durability. Along with easy and safe tool-free blade changes, this knife can be set up for both right- and left-handed use.

Use the Fully-Automated Self-Retracting Safety Knife for enhanced protection against injuries in the workplace.
