Abstract
Abstract A die is provided for cutting at least one but less than all of the layers of a plurality of layers of paper such as a sheet of lables or the like. A raised cutting edge of the die is rounded so that the portions of the cut layer or layers on either side of a cut made by the cutting edge are cammed away from each other so that the backing or other layers are neither cut nor crushed. The die may be made by etching according to conventional procedures followed by moving the usual cutting edge obtained through a spray of etching fluid at such a rate that the cutting edge is naturally rounded.
