Tools and methods of making tools that are swung toward a work-piece are more accurate and/or safer to use because of a moveable grip provided on the tool handle. The tool handle slides through the moveable grip, with minimal or no rotation or shifting relative to the grip. The movable grip eliminates the need for the forward hand of the user to loosen its grip during portions or all of the swing, eliminates the need for the hand itself to slide along the surface of the handle, and, importantly, greatly reduces or eliminates the chance that the tool and the impact head of the tool hand will rotate or shift relative to user's hand(s). The moveable grip and handle are preferably rigid and hard and mated in shape and size so that rotation and shifting is reduced or eliminated. The preferred embodiment includes one or more control members for retaining or latching the moveable grip in one or more desired locations on the handle, so that the moveable grip may be prevented from sliding along the handle until the user desires it to slide.
