ABSTRACT:
A utility knife has a disposable blade cartridge in its handle that has front and rear blade compartments. Each compartment is sized to store a plurality of blades in side-by-side relation. Fresh blades are disposed in the front compartment and one end of each is advanced one at a time substantially out of the compartment into operative position 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the active blade is to be replaced, it is moved by the carrier into the rear compartment, and a new blade may then be withdrawn from the front compartment into the operative position. The active blade when not in use is partially withdrawn into the front compartment.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. When all are used, a new cartridge replaces the old in the knife
