  • Apparatus for manipulating chopsticks
    Patent number: 5486029
    Abstract: An apparatus for manipulating chopsticks is described which can be easily manufactured out of a polymer plastic tube, such as a drinking straw. The tube or straw is divided into a central portion and two wing portions by two transverse cuts. The size of the central portion is selected in accordance with a desired spacing between two chopsticks. Each of the wing portions has an axially extending bore of a size sufficient to accommodate a chopstick in friction fit relation. The transverse cuts extend only partially through the thickness of the tubular body leaving connective strips between the central portion and each of the two wing portions that serve as living hinges.
