This revolutionary cutter is equipped with a long-lasting, rugged, cast metal safety blade / guard system, designed specifically for continuous or occasional (top) carton cutting and enhanced with additional safety features throughout. The safety blade / guard activation system safely extends the blade & guard in tandem, protecting against exposed razor blade cuts, while cutting. Additionally since the blade / guard extends for cutting only, the spring-back action eliminates the risk of cutter injuries, which in the end increases profits and eliminates medical insurance claims. Designed as a universal right and left handed cutter, it can be switched from right to left hand, as easily as a blade change. Increase profitability using a single, 3-in-1 tool, that is equipped to handle the most demanding stocking, and warehouse tasks efficiently.
