  • Patent number: 5365811
    Abstract: A single unit multipurpose hand tool structured to allow for the manual manipulating of fasteners and the removal of wheel bearings on in-line roller skates. The multipurpose tool includes a rigid plastic center handle structured generally of a three armed star having flattened distal ends from which metal tool tips extend. The center handle includes curving sides connecting each arm so as to provide smooth curved surfaces which comfortably fit the human hand and thereby allow high manual rotational leveraging of the tool tips when manipulating fasteners. The multipurpose tool provides a flat head screw driver, a hex key, and a phillips screwdriver having an adjacent wheel bearing pusher having two abutment shoulders, and thereby the compact and lightweight tool provides all of the most commonly needed tools associated with the maintenance of in-line roller skates.
