ABSTRACT:
A combination tool comprises an elongated lever having a handle at one end, two divergent fingers at the other end, and an aperture between the two ends adapted for engagement with a nut. One of the fingers includes a distal end and claw in spaced relationship thereto which cooperate to provide a fulcrum for movement of the lever, thereby to facilitate the removal and replacement of nuts which are locked on a threaded shaft by a locking member having bendable tabs projecting outwardly therefrom.
