Abstract
A tubular upstanding wall of a predetermined height and defining a central aperture has an integrally formed, inwardly facing flange on its upper end, and an integrally formed, outwardly facing flange on its lower end. The inwardly facing flange has a sharpened cutting edge thereby forming a razor blade. One or more razor blades are positioned through apertures in a top member and the outwardly facing flange cooperates with the lower face of the top member to control the vertical position of each razor blade.
