  • Patent number: 6625890
    Abstract: A cutlery device is provided having a blade with a sharpened edge and an opposite, unsharpened back. The cutlery device also includes a tang extending from the blade which is at least partially enclosed in a handle. The tang has a tapered thickness to produce a cutlery device that is balanced when grasped with some fingers on the handle and some fingers on the blade. The back of the blade is curved so that a finger may be comfortably pressed against the back. The handle is curved for comfort and pieces of the handle are secured on the tang with rivets of varying length to accommodate the shape of the handle. A sharpening aid is also provided for the cutlery device which has at least one angled wall for positioning a sharpening surface at a sharpening angle, permitting the cutlery device to be held with the blade positioned vertically during a sharpening operation.

  • Patent number: 5924433
    Abstract: A dishwasher construction having a molded one piece tub with integrally molded reinforcing ribs on an outside surface of the tub, the reinforcing ribs being hollow members formed by gas injection molding. At least one of the reinforcing ribs can be fashioned as a hollow conduit for transferring water from a bottom mounted pump to a top mounted wash arm of the dishwasher, or from a drain pump to a drain outlet. By using hollow reinforcing members molded integrally with the tub, an external upper wash arm conduit is avoided which can have external leakage, and an internal upper wash arm conduit is avoided which tends to restrict the working space within the dishwasher and can trap food and be otherwise functional and unappealing to the consumer.
