ABSTRACT:
An improved multi-hole punch is provided in which the vertical distances between the lower ends of a multiplicity of rod cutters are gradually increased from one end to the other end of the lateral row in which the plurality of rod cutters is arranged. Thus, the rod cutters plunge into paper sheets supported on the base of the punch sequentially in the direction in which the vertical distances of their lower ends from the aforementioned portion of the base increase.
