Safe utility knife that slides back in automatically. The blade of this sturdy safety knife pops up by pushing the slide button and retracts back inside when you release the slider. Made for right-handers. Comes with an easy-to-replace SK4 0.6 mm blade. Perfect for warehouses and food industries, since the blade won't accidentally break off into opened packages or stick out from its sheath during transport.
