Each of the triangular elements includes an elongated element composed of a suitable porcelain material which includes at least three substantially flat surfaces which are joined together by a small radius. Each of the star-shaped openings are angularly disposed with respect to the horizontal at a predetermined angle so as to orient the sharpening element to a desired degree with respect to the edge to be sharpened when the edge is held in a vertical plane.</p> |
