ABSTRACT:
The present invention relates to a punch for office use for making a pair of holes at first or second predetermined spaced apart distances in a card, or like paper to be punched by a pair of punching blades. A pair of right and left blade supporting members each support a punching blade. Each of the punching blades has a longitudinal axis that deviates from the longitudinal axis of the blade supporting member. A punch for either narrow or wide punching can be manufactured by changing the right and left positions of the pair of right and left punching blade supporting members.
