Golf club heads are described having a club head portion, a shaft portion connected to the club head portion, and a grip portion connected to the shaft portion. The club head portion has a heel portion, a sole portion, a toe portion, a crown portion, a hosel portion, and a striking face. The striking face can have a center face roll contour, a toe side roll contour, a heel side roll contour, a center face bulge contour, a crown side bulge contour, and a sole side bulge contour. The toe side roll contour can be more lofted than the center face roll contour. The heel side roll contour can be less lofted than the center face roll contour. The crown side bulge contour can be more open than the center face bulge contour, and the sole side bulge contour can be more closed than the center face bulge contour.

A golf club has a first shaft coupled to a club head, a second shaft configured to slidably engage a portion of the first shaft, a grip coupled to the second shaft, and an adjustable length shaft assembly received by the second shaft and configured to allow a portion of the first shaft to slide in relation to the second shaft in a first configuration, and to restrict a portion of the first shaft from sliding in relation to the second shaft in a second configuration. The grip is restricted from rotation about the first shaft or the second shaft as the first shaft slides in relation to the second shaft.

Embodiments of golf club heads and methods to manufacture golf club heads may include a golf club head having a body portion, a first mass portion, and a second mass portion. The first mass portion has a first mass portion first end and a first mass portion second end such that a distance between the first mass portion first end and the first mass portion second end defines a first mass portion dimension. The second mass portion includes a second mass portion first end and a second mass portion second end such that a distance between the second mass portion first end and the second mass portion second end defines a second mass portion dimension. The second mass portion dimension may be substantially greater than the first mass portion dimension, and a total mass of the second mass portion may be greater than or equal to three times a total mass of the first mass portion. Other examples and embodiments may be described and claimed.

A golf club connecting apparatus for securely connecting a golf club shaft and a club head having a hosel portion is disclosed. The apparatus could be advantageously employed with various types of golf clubs. The apparatus comprises a hosel adapter, a shaft adapter, and at least one fastener, for example, a nut. The hosel adapter is configured to insert into the hosel portion such that the hosel adapter is positioned within the cylindrical sleeve of the hosel portion. The shaft adapter is securely affixed to the terminal end of the golf club shaft, wherein the shaft adapter is configured to insert into the hosel adapter via a longitudinal bore. The fastener is configured to threadably engage to the hosel adapter via the plurality of threads, thereby securing the club head and the golf club shaft together by inserting the shaft adapter into the hosel adapter.

A hockey-stick includes a blade and a shaft. The blade includes a heel region, a toe region spaced longitudinally from the heel region, and a mid-region located between the heel region and the toe region. The blade optionally also includes a hosel to which the shaft is attached. One or more tuning rods or similar structures are positioned in the blade to increase the blade's stiffness to substantially match the stiffness of the shaft. The tuning rods are optionally located in the mid-region of the blade and may extend into the hosel and, in some cases, into the shaft or the toe region.

A golf club head includes a body having a face plate having a strike surface and an opposing interior surface, a rear end, and a sole connecting the faceplate with the rear end. The face plate, the rear end, and the sole partially define a cavity. An insert is positioned within the cavity, the insert presenting an insert surface facing the interior surface of the face plate and spaced therefrom.
