  "abstract": "19 22456161_1 (GHMatters) P119302.AU.2 An anvil for an impact mechanism, where the anvil includes wings that taper at a taper angle of about 5 degrees to about 30 degrees. The anvil may also include a shaft extending from the wings, and a drive end adapted to transfer and apply torque to a work piece. The wings of the anvil also include wing impact surfaces that receive rotational impact forces from a hammer. For example, the hammer contacts and applies torque to the wings of the anvil.",
