ABSTRACT:
A retractable cutting implement, such as a utility knife, comprises a sleeve-like handle member having a cavity portion with the handle member being open at the base and at one end through a first longitudinal slot. A carrier member is pivotally mounted to the handle for pivotal movement into and out of the cavity with the carrier member being resiliently held within the cavity when it is pivotally moved into the cavity for substantially closing the cavity. The carrier member comprises a substantially enclosed longitudinally extending chamber with a passage therein in communication with the one end of the first slot in the handle member and a blade carriage member is slidably mountable in this chamber for slidable movement toward and away from the passage. The blade carriage member has a plurality of studs at the end thereof opposite the pivotally mounted end of the carrier member adapted to support a perforated cutting blade having a top edge and a bottom edge for slidable movement of the blade into and out of the first slot one end through the passage when the implement is in the closed position. The carrier member includes an outer edge having a guide channel portion which is disposed on the carrier for protecting a portion of the cutting edge of the blade when the blade is supported on the studs. The handle member has a second longitudinal slit therein with a button disposed on the blade carriage member and extending through the chamber and into this slit in the closed position of the implement. The button is movable along the slit to effectuate movement of the blade carriage member to extend or retract the blade from the knife. The carrier further includes a resilient clip portion adapted to store and resiliently hold perforated cutting blade replacements for the supported blade with the resilient clip being pivotally insertable within the handle. The carrier, the handle and the blade carriage member are all preferably composed of metal, such as steel.
