An iron golf club head comprised of a head body 10 made of light metal such as titanium and containing a plurality of weight members 16. The head body 10 includes a front surface 13, a rear surface 13a, a cavity 12 disposed at the rear surface 13a, and a plurality of holes 15 disposed in the head body 10 at the rear surface 13a between a lower side wall 12b of the cavity 12 and a sole 14 of the head body 10 at predetermined intervals between a toe part 17 and a heel part 18. The center axis of each hole 15 is oriented substantially parallel to the sole 14 of the head body 10. The weight members 16 are press-inserted into the holes 15 in a direction going toward the front surface 13 of the head body 10 to a predetermined depth. Each weight member 16 is made of a material having a heavier specific weight than the light metal used for the aforesaid head body 10. Tungsten or tungsten alloy can be used as the material for the weight members 16. The combined weight of the weight members 16 does not exceed forty percent of the weight of the entire head.

A golf club (40) having a club head (42) with a face component (60) and an aft body (61) is disclosed herein. The face component (60) has a striking plate port ion (72) and a return portion (74). The aft-body (61) is composed of a crown portion (62), a sole portion (64) and optionally a ribbon section (90). The face component (60) is composed of a metal material, and the aft-body (61) is preferably composed of a non-metal material such as a composite material or a thermoplastic material. The face component (60) is bonded to the aft-body (61) with a leading edge (180) of an undercut portion (62a and 64a) of the aft-body positioned a distance of 0.100 inch to 0.500 inch from the interior surface (60a) of the face component (60) in order to reduce the stress on the bonded joint of between the face component (60) and the aft-body (61). The club head (42) has a volume in the range of 290 cubic centimeters to 600 cubic centimeters, a weight in the range of 165 grams to 300 grams, and a striking plate portion (72) surface area in the range of 4.00 square inches to 7.50 square inches.

A weight adjustable golf club head is provided. The club head has a trough at a lower part of the club head's back and a weight positioned inside the trough. The trough is arranged to follow the curvature of the club head's bottom. The trough has a tapered mouth along the surface of the club head and a base. There is an insertion hole at a position along the trough. The weight could be inserted into the trough through the insertion hole, and then slid along the trough. The weight contains a seat, a bolt, and a loading ring. The seat has a locking rim and the positioning rim which are inside the trough's base and mouth respectively when the weight is slid into the trough. The seat's body and the locking rim have a number of breaks so that the locking rim could be stretched. When the bolt is screwed into or out of the seat, the locking rim would be stretched or retracted, so that the weight could be locked or un-locked in the trough. The loading ring is put around the seat and could be made of various types of material. By adjusting the position of the weight along the trough and changing the loading ring, the club head's center of gravity could be adjusted to suit a golfer's specific stance, habit, and the specific trajectory required.

A system for converting readily available standard off the shelf golf club parts into a interchangeable golf club system. A conversion system consists of a head insert which can be glued into the hosel of a standard golf club head. A shaft insert having a central flange is insertable and glueable into place on a standard shaft of a golf club. The shaft insert and the head insert forming a quick connect to attach the shaft to the golf club head. Through the use of different club heads representing the full range of woods, irons, and putter, each having a head insert pre-installed, the club may have emulating any club by attaching the desired club head. A shaft length adjustment is made by a cooperating pin installed in the top of the shaft and slidable within a number of slots provided in a telescoping sleeve slidable over the shaft.

A golf club having a hollow golf club head which is filled with a gas under pressure. The interior surface of the golf club head is coated with a solidified layer of plastic material. The pressurized gas permits the use of thinner face plates by compensating for forces generated when the face plate strikes a golf ball. The plastic layer is preferably applied through the process of rotational molding using a thermoplastic material.

A club head for a golf club comprises a strike face and an outer shell. The strike face and the outer shell define a head volume of the club head. The club head has a first axis that extends generally horizontally and parallel to the strike face, a first moment of inertia about the first axis, a second axis that lies generally vertically and perpendicular to the first horizontal axis, a second moment of inertia about the second axis, and a center of gravity lying below a horizontal centerline of the club head. The first moment of inertia in units of kg-mm² is greater than or equal to approximately 77 plus 0.46 times the head volume in units of cm³.

A golf club having features that permit easy customization by consumers is disclosed herein. The golf club includes at least one weight port, a ribbon, at least one removable weight port ring, and at least one removable ribbon insert.
