  • Patent number: 6264571
    Abstract: The present invention teaches a dynamically balanced putter with a sliding hosel to ensure that the center of mass of the putter lies on the axis defined by the putter shaft. The putter head includes a longitudinal slot which mates with an elongated “dovetail” tab on the hosel to slidingly position the axis, hosel, and putter head such that the aforementioned balancing objective is achieved. In a preferred embodiment, a dovetailed tab is mated with a mating slot, and the putter head is slid into a position with minor adjustments following an initial balancing, which results in a dynamic balancing of the entire putter. By rotating the putter about the shaft or suspending the shaft and evaluating the angle against vertical, minute adjustments can be made by sliding the putter head along the dovetailed tab until complete balancing is achieved. Once the putter head has been fixed using either a strong adhesive or other fixing means, the putter can then be used in its intended manner.
