ABSTRACT:
A paper cutter is provided with a stationary blade and a movable blade unit. The movable blade unit is provided with a circular blade for cutting a rounded corner of a sheet of paper and a corner cutter blade for cutting the corner edge of the sheet of paper. The movable blade unit is inserted in a movable blade inserting hole provided in the stationary blade, the corner of the paper is inserted in a slit cut in the stationary blade which intersects with the movable blade inserting hole. During the cutting of the corner by the circular blade, the corner of the paper is tensioned between the circular blade and the corner cutter blade. As a result, the paper is cleanly and uniformly cut and the force required to cut the paper is decreased as compared to conventional paper cutters.
