Abstract
Abstract A fish gaff comprises a gaff hook releasably attached to a handle by either spring tension or compression. Depending upon the weight of the gaffed fish, the hook may be partially released from the handle to permit its relative rotation. This construction permits a user to maintain control of a fish without the gaff being twisted, bent or jerked out of the user's hands. In a first embodiment, spring tension is utilized to pull the hook into engagement with a locking slot formed in an interior portion of the handle. In a second embodiment, spring compression is utilized to maintain the hook in a locked position relative to the handle.
