ABSTRACT:
A knife particularly for opening corrugated board cartons efficiently and safely without damaging the carton contents includes a forward end receptor slot for a standard single edge razor blade which positions the cutting edge of the blade below and forwardly of the hand grip portion of the knife for safety. An automatically retractable and recloseable blade guard having a cantilevered connection with the hand grip portion of the knife also serves as a cover for a blade storage compartment in the hand grip portion and is permanently attached to the knife to preclude loss. Depth of cut is limited to avoid damaging carton contents.
