Abstract: The invention is a device for opening heat sealed cellophane bags and packages. It is formed of a support bracket assembly, a doubled edged razor blade, and a safety guard assembly. The support bracket assembly is secured to the bottom surface of a cabinet or shelf. One end of the razor blade is inserted into a horizontal slot on the front wall of the support bracket assembly and it is secured in position by a screw. The other end of the razor blade is inserted into a horizontal slot in a vertical wall surface of the safety guard assembly and it is secured therein by a screw. The safety guard assembly is thus entirely supported by the razor blade and at a predetermined spaced distance from the front wall of the support bracket assembly so that a sealed cellophane bag or package can be drawn between their respective wall surfaces thus allowing the razor blade to cut off the heat sealed end of the bag.
