  • Patent number: 8393069
    Abstract: A writing instrument comprising a writing utensil and associated handles interconnected to each other to allow a user to selectively position the writing utensil in either an extended position of use or a closed position of storage, as well as a variety of positions there between. In an open position, the handles may be positioned adjacent one another with the writing utensil extended longitudinally away from the adjacent handles in a position of use. In a closed position, the handles may be positioned adjacent to the longitudinal length of the writing utensil, with the writing utensil at least partially enclosed between the handles in a position of storage. The rotation of the handles about the writing utensil allows a user to manipulate the handles in a variety of ways, similar to that of a “butterfly knife” or similar device comprising balisong style openings.
