Abstract
A guided utility knife that alternates between a carton tray cutter and a conventional utility knife is provided herewith. The knife comprises two rotatable guide portions that are hingedly attached to the housing. Each guide portion flips laterally, away from the cutting blade from its unfolded position to its folded position. Each guide portion further occupies a channel on the exterior surface of the housing. Magnets are provided in the housing to secure the guide portions in both the folded and unfolded positions.
