A cutting apparatus has been produced that eliminates the common occurrence of raw razor blades contaminating everything from food and food products to garbage cans to shelves in retail stores. Furthermore, the cutting apparatus comprises a guard assembly that, when activated, opens the blade cover and allows only one cut to be made with the exposed blade before the unidirectionally-locking blade cover snaps back over the exposed blade, thus preventing laceration-related accidents. In addition, if the operator continues to activate the guard assembly (squeezing, pulling and/or depressing the trigger and/or releasing the trigger and continuing to hold it in the released position during and after the cut has been made) after one cut has been made with the exposed blade, the unidirectionally-locking blade cover will still snap back over the exposed blade, despite the position of the trigger. Once the blade cover snaps back over the exposed blade, the locking device is activated and acts to hold the blade cover securely over the blade until the blade assembly is further activated by releasing the trigger from the depressed position and depressing, releasing, squeezing or pulling the trigger once again.
