ABSTRACT:
A body has a recess in one surface and within which is disposed a non-circular cutting element retained therein by an epoxy. The non-circular cutting element has its cutting edge formed by beveling its inner surface. The non-circular cutting element extends sufficiently beyond the one surface of the body to be able to penetrate into a face plate, which is utilized with a stoma and in which the non-circular opening is to be cut for use with the stoma of the same shape. A circular template of a clear plastic is removably mounted on the one surface of the body and has a plurality of circles of varying diameters thereon to center the non-circular cutting element relative to a face plate adhesive blank of one of the varying diameters to enable cutting of the same non-circular opening in the adhesive blank. The template has a pair of parallel lines along its circumference to align with a tab on the adhesive blank.
