A cutting element includes a modified gilmoid having two planes defining a plurality of cutting edges thereon, and a first support extending from a central area of a first of the two planes and a second support extending from a central area of a second of the two planes. The supports are sized and positioned such that when the cutting element is resting against a planar surface such that one of the plurality of cutting edges and the first support are in contact with the planar surface the first plane forms an acute angle with the planar surface.
