  • Cake layer cutter
    Patent number: 4213241
    Abstract: A cutting blade extends between the legs of a U-frame. The legs have incrementally adjustable length-wise extensions so that the distance between the blade and the ends of the leg extensions can be adjustable. By this means the height of the blade above a table upon which a cake is supported can be predetermined so as to cut cake layers at predetermined standard thicknesses.
