ABSTRACT:
A hand-held cutting device is provided for opening cartons, such as cardboard boxes, without damaging the contents within the carton. The cutting device comprises a handle having an elongated flat bottom surface which is adapted to slide along the outer surface of the carton during a cutting operation. A cutting blade is secured to the handle and extends outwardly through an opening in the bottom surface of the handle for engaging and cutting the carton. A guard is secured to the cutting blade across its outwardly extending end and includes a portion extending forwardly of the cutting edge of the cutting blade. This forward portion of the guard is curved towards the handle and serves to deflect the contents of the carton away from the cutting blade during a cutting operation. Preferably the upper front edge of the guard forms a second cutting edge so that the guard easily pierces the carton during the initiation of a cutting operation.
