An anvil is slidably disposed on one of the mount bases with the anvil being freely rotatable with respect to the mount base. A knife base is slidably disposed on the other mount base and is keyed to the other mount base for rotation therewith, the knife base having a cutting tool disposed thereon for cutting holes in the paper sheet. A pair of identically shaped retaining plates are fixed to each of the mount bases with one of the retaining plates engaging the anvil for positioning the anvil on one of the mount bases and the other retaining plate engaging the knife base for positioning the knife base on the other mount base.
