A game stick for use with a golf ball, the game stick including a shaft having a proximal end, a distal end, and a longitudinal axis extending between the proximal end and the distal end and a head coupled to the distal end of the shaft. The head has a first sidewall, a second sidewall, and a bottom wall defining a channel extending radially from the longitudinal axis, the channel configured to receive the golf ball. The game stick further includes surface disposed on an exterior surface of the head, the striking surface being comprised of a different material than the head.

A golf club head includes a club face and a body. The club face is formed from a metallic material and includes a first, hitting surface, a second, rear surface that is opposite the first surface, and a flange that is separated from the second surface by a transverse distance. The body is formed from a polymeric material and includes a crown, a sole, a hosel, and a face support. The club face and the body cooperate to define a closed volume, and the face support extends to opposing sides of the flange and is operative to couple the club face to the body.

Iron-type golf club heads can have a high-COR face portion with an optimized face thickness profile that maximizes selected performance characteristics, such as ball speed, ball spin or ball trajectory angle, while maintaining certain required constraint properties, such as keeping stresses low for durability. Such face portions can have certain regions that are significantly stiffer than other regions of the face portion. For example, a low region of the face portion can be significantly stiffer than a high region of the face, or one quadrant of the face can be significantly stiffer than other quadrants of the face. Disclosed face thickness profiles can feature irregularly shaped contours that maximize the distribution of material in the face for optimal performance characteristics within defined constraints.

A golf club head that is capable improving on the inertia properties of a golf club head all while also improving the Center of Gravity (CG) location is disclosed herein. More specifically, the golf club head in accordance with the present invention achieves a relative low Moment of Inertia (MOI) about the Z-axis (MOI-Z) as well as a relatively low MOI about the Shaft-axis (MOI-SA), all combined with a high MOI about the X and Y-axis (MOI-X and MOI-Y) and maintaining a consistently and relatively low CG location measured along a direction tangent to the hosel axis along the X-Y plane (CG-B).

An apparatus for a ball bat and a ball bat comprising at least one disc member that defines an outer diameter corresponding to an inner diameter defined by the ball bat to create a fit within close proximity between the at least one disc member and the ball bat. The at least one disc member can be located within the barrel portion of the ball bat. The at least one disc member can include at least one solid disc member that is located within a sweet spot of the ball bat. In some embodiments, the apparatus for a ball bat and the ball bat can further include an at least one insulation foam member. The at least one insulation foam member can separate the at least one disc member. The at least one insulation foam member can define a hollow center portion.

Embodiments of golf club heads with energy storage characteristics are presented herein. In some embodiments, a golf club head comprises a hollow body comprising a strikeface, a heel region, a toe region opposite the heel region, a sole, a top rail and an inflection point. The inflection point provides increase bending of the strikeface thereby providing performance enhancement over clubs without an inflection point.

Golf clubs heads having a forward portion located at a front side of the golf club head and an aft portion located rearward of the forward portion and joined to the forward portion. The front portion includes a forward joint section and the aft portion includes an aft joint section. The aft portion also includes an aft rib attached to an interior surface of the aft portion, the aft rib extends, from an interior surface of the aft joint section, in a direction away from the striking face. The golf club head may also include a crown the crown having an areal density of less than 1000 g/m.sup.2 and made from a structure comprising an inner layer, a middle layer in contact with the inner layer, and an outer layer in contact with the middle layer.

A golf club head includes a loft no less than 40 degrees; a striking face; a virtual center plane that is vertical and perpendicular to a virtual striking face plane and includes a face center; a rear face; and a recess. The recess extends in a heel-to-toe direction along an upper sole surface and has a depth that varies in the heel-to-toe direction such that a first depth corresponds with a first location heel-ward of the face center and a second depth corresponds with a second location toe-ward of the face center, the first depth being no less than 10 mm and greater than the second depth by at least 5 mm. An insert is received in the recess. And a center of gravity of the golf club head is spaced no greater than 5.0 mm from the virtual center plane measured in the heel-to-toe direction.

A putter head includes a forwardly facing putting face extending in a longitudinal direction between a heel end and a toe end, and the putter head includes a front part and a rear part. The front part includes: a forward-facing surface including the putting face and a slot provided in an upwardly facing surface of the front part. The slot is configured to take up a hosel for connecting a shaft to the putter head and to arrange the hosel at different longitudinal positions between the heel end and toe end of the putter head. The slot includes a bottom surface, and a rearward-facing surface. The rear part includes an upward-facing surface having connecting means for connecting one or more weights to the rear part of the putter head at different longitudinal positions between the heel end and toe end of the putter head.
