    (54) A punch


    (57) This invention relates to a punch for making holes in paper. The punch comprises two parallel support plates (1, 3) having aligned holes (5, 6), and a punching means (7) displaceable within the holes. The outer end of the punching means is provided with a round press button (9) which also serves as a spring for the punching means. The punching of paper with punches known from the prior art is heavy due to the great force required for the deformation of the press buttons. The punching can be made considerably lighter by using flexibly buckling press buttons (9).
