Adjustable balance weighting systems (10 and 110) are provided for adjusting the weighting and balance of golf clubs of either the "iron" or the "wood" types. An eccentric weighting means is mounted on or in the club head (14 or 74) so as to be rotatable and provide a mechanism by which the center of mass, and therefore the sweet spot, of the club head (14 or 74) may be varied. In the case of an iron-type club head (14), an eccentrically weighted disk (32) is mounted in a substantially vertical orientation on the rear face (24) of the club head (14). In the case of a wood-type club head (74), a similar disk (82) is mounted in a horizontal orientation in a recess (80 or 89) in a top or bottom surface (78 or 87) of the club head (74). When adjustment is needed, a screw (68 or 86) is conveniently loosened so that the disk (32 or 82) may pivot and be turned to a desired orientation, thereby causing more weight to be transferred to either the toe or heel of the club head (14 or 74), as necessary, to correct a "slice" or a "hook," respectively. In an alternative embodiment for wood club heads (112), eccentric weighting is provided by a rotatable sole plate (130) with an attached weight (156) eccentrically located thereon. In a further enhancement to the adjustable balance weighting system, there is also provided, in the case of wood clubs, an oversized club head (112) of a substantially ellipsoidal shape. The redistribution of weight afforded gives greater controllability and allows a more effective use of the already increased sweetspot provided by an oversized club head.

A golf club features a hollowed club head having an insert movably mounted therein. The insert is weighted so that it works like a pendulum during a user's swing of the club. The insert has a flat face that shifts to present a face to the ball that corrects for improper technique.

An adjustable balance weighting system (10) is provided for adjusting the weighting and balance of a golf club of either the "iron" or the "wood" type in order to encourage the golf club to be in tune with the golfer's swing and/or to correct any deficiencies that may exist therein. An eccentrically weighted balancing disk (32 or 82) is mounted on or in the club head (14 or 74) so as to be rotatable about a first Allen screw (60 or 84) and provides a mechanism by which the center of mass, and therefore the sweet spot, of the club head (14 or 74) may be varied. In the case of an iron-type club head (14), the balancing disk (32) is mounted in a substantially vertical orientation in a cavity (30) on a cavity back wall surface (40) at the rear face (24) of the club head (14). In the case of a wood-type club head (74), the balancing disk (82) is mounted in a horizontal orientation in a recess (80) in the top surface (78) of the club head (74). When adjustment is needed, a second Allen screw (68 or 86) is conveniently loosened so that the balancing disk (32 or 82) may pivot and be turned to a desired orientation, thereby causing more weight to be transferred to either the toe or heel of the club head (14 or 74), as necessary, to correct a "slice" or a "hook," respectively. Provision is also made for the use of the adjustable balance weighting system (10) in the context of the "fitting" of golf clubs so that a permanent adjustment is made.

A golf putter is provided having a head and shaft. The head is provided with spaced-apart weights which extend at least about 35% of the maximum distance between the front face and back edge of the head. The shaft enters the head at a point at least about 65% of the length of the putter away from the front face. The shaft is angled toward the front face of the head and toward a user grasping the shaft.

A putter head includes a face portion, at least one first aiming marker, and a contrast portion. The first aiming marker appears substantially parallel to a face surface of the face portion. The contrast portion substantially contrasts with the first aiming marker in appearance. The contrast portion is disposed adjacent to the face portion.
