ABSTRACT:
A utility knife has a blade cartridge that has front and rear blade compartments. Each compartment stores a plurality of blades. Fresh blades are disposed in the front compartment and are advanced one at a time out of the compartment by a carrier that is controlled by an actuator on the handle. When the active blade is to be replaced, it is moved by the carrier into the rear compartment, and a new blade may then be withdrawn from the front compartment into the operative position. The active blade when not in use is withdrawn into the front compartment. The cartridge is reversed when the one end of all the blades in the front compartment are used, placing what was the rear compartment at the front, and the unused end of each blade is advanced into the operative position and when used they are each moved to the rear compartment.
