A hand-operated combination two-and-three-hole puncher for making holes in paper and other sheet materials is shown and described. The two-hole punch assembly and the three-hole punch assembly are fixedly disposed on the common platform either in-line, or at a predetermined angle, to each other in such manner that both punch assemblies share a common punch subassembly and a common foot. The common punch subassembly could be activated using either the press lever frame of the two-hole punch assembly or the press lever frame of the three-hole punch assembly thus enabling the common punch subassembly to punch a hole in the process of the two-hole perforation or the three-hole perforation without the readjustment.
