A golf club head with a hosel hole cover that helps improve the performance of the golf club head is disclosed. More specifically, the present invention relates to a golf club head having a hosel hole cover at a bottom portion of an interchangeable connection system that not only provides improved performance of the golf club head by strategically utilizing an existing opening to adjust the weighting of a golf club head, but it also improves the aerodynamics of the golf club head by eliminating undesirable recesses that could be detrimental to the aerodynamics of a golf club head.

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).

Embodiments of golf club heads and methods to manufacture golf club heads are generally described herein. In one example, a golf club head may include a body portion having a front portion, a rear portion, a toe portion, a heel portion, a top portion, a bottom portion, a face portion, and a periphery. The bottom portion may include a forward portion and a rear protrusion at or proximate the rear portion. The rear protrusion may project downward from the periphery and extend longitudinally in a rear-to-front direction. The rear protrusion may include a front-side portion. A toe-side portion may extend rearwardly from the front-side portion towards the rear portion. The rear protrusion may also include a heel-side portion extending rearwardly from the front-side portion towards the rear portion. A weight port may be defined by the rear protrusion. Other examples and embodiments may be described and claimed.

Described herein is a tour iron having a golf club head with a faceplate, a body, and an insert. A sole, top rail, rear, and the faceplate enclose a cavity within the body. The cavity can house the insert. The insert can comprise a low-density material, allowing weight to be concentrated around the peripheral edge of the golf club head. The insert can further comprise multiple materials to improve sound and feel. The rear of the golf club head has an inflection seam running from the heel to the toe. The golf club head has an upper portion, above the inflection seam and a lower portion below the inflection seam. The lower portion can have a depth greater that the upper portion depth. The faceplate, body, and insert can be formed of different materials having different densities. The golf club head has a comparatively high moment of inertia and a low center of gravity. Other embodiments and methods are described herein.

A golf club head is described having a body defining an interior cavity and comprising a heel portion, a toe portion, and a sole portion positioned at a bottom portion of the golf club head, and a crown positioned at a top portion. The body has a forward portion and a rearward portion. A non-metallic striking surface is positioned at the forward portion of the body.
