ABSTRACT:
A cutter operative to pierce and cut a sheet of material includes a handle and a body portion coupled to the handle. The body portion includes two puncture fingers having tips for piercing the sheet of material and two blades for cutting two parallel cuts in the sheet of material. In a method of installing a zipper on a sheet of material, left and right portions of a zipper are applied to a sheet of material. A swath portion of the sheet of material is cut having two parallel, spaced-apart cuts between the left and right portions of the zipper. In this manner, zipper installation is established in a manner that avoids formation of flap of material that would otherwise remain between the left and right flanges of the zipper.
