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.
A golf club comprising a head, a hosel, and a shaft, and a club center of mass defined by a relative position and mass of said head, hosel, and shaft, the axis of the shaft defining an axis of revolution for dynamically balancing the golf club, and where the relationship between the head, the hosel and the shaft is such that the axis of the shaft passes through the club center of mass, the club head including an I-beam profile defined by a cross section of the putter head from a vertical slice perpendicular to a plane defined by the striking surface of the putter head, the I-beam profile defining first and second cavities on either side of said I-beam profile body, and first and second striking surface cover plates disposed on a front and back of said golf club head enclosing said first and second cavities.
A golf club comprising a head, a hosel, and a shaft, and a club center of mass defined by a relative position and mass of said head, hosel, and shaft, the axis of the shaft defining an axis of revolution for dynamically balancing the golf club, and where the relationship between the head, the hosel and the shaft is such that the axis of the shaft passes through the club center of mass, wherein said head includes a slot on an upper surface and extending from a middle portion to an end of said head, said slot having a necked portion along said upper surface, and said hosel includes a dovetail member sized to be inserted slidingly into said slot such that said dovetail member is rigidly fixed in said slot save said sliding motion, whereby the relative positions of said hosel and said head are rigidly fixed in said slot at a location where the center of mass intersects the axis of the shaft.
