OLFA Self-Retracting Safety knives - Safety experts rely on it, so should'nt you?

OLFA offers high-quality, safety knives with a commitment focused on accident prevention.    

The Olfa SK4 safety knife incorporates an automated blade retraction mechanism that pulls the blade fully into the handle at the end of each cutting stroke for safety. To use the mechanism, simply extend the blade and start the cut. The downward pressure and pulling force keeps the blade extended along the entire cut. As soon as the blade exits the cut, the mechanism instantly retracts the blade. The retraction mechanism requires no worker intervention. 

Suitable for both right and left-handed users. Perfect for high traffic shipping and receiving departments.
