  • Patent number: 4345516
    Abstract: A cooking and cutting kitchen implement apparatus has a hollow cylindrical ring member having one edge thereof formed into an angular cutting edge for cutting circular shapes, and a flat edge on the other edge thereof adapted to be placed on a grill for cooking an egg, or the like, therein. The ring member has a handle attached thereto with a spring clip connected into a pair of openings in the exterior of the ring and positioned so that the handle will be supported on the edge of the ring member to keep the handle off the grill when used for cooking. The handle may also be used on opposite side after turning the ring over. The ring may be lined with a solid lubricant polymer to prevent an egg, or the item therein, from sticking to the inside of the ring and the flat edge of the ring may have an annular groove therein.
