Abstract

In one embodiment, a golf club head is presented having a sole with three recessed cavities for attachment to a hosel-bending tool. In another embodiment, a golf club head is presented having a sole that includes one predetermined contact area proximal to the toe edge of the sole. In another embodiment, a golf club head is presented having a sole in which pads of material are incorporated that may be milled to vary the relief of the sole and to modify mass characteristics of the club head. Yet another embodiment presents a golf club head having a body with a cavity to receive a cartridge that has a constant density and weight.

Claims

1. A golf club head, the club head comprising:

a body having a face, a sole, a crown and a skirt joining the face, sole and crown,

wherein a plurality of pads of material are disposed onto the sole and wherein said material may be milled, polished, shaved, or otherwise removed from said pads to vary the mass property of the club head.

2. The golf club head of claim 1, wherein said pads are disposed onto the external side of said sole.

3. The golf club head of claim 1, wherein each pad has surface area between about 100 mm² and about 200 mm².

4. The golf club head of claim 1, wherein said pads have individual depths between 5 and 15 mm.

5. The golf club head of claim 1, wherein said pads of material are disposed internal to the golf club head.

6. A golf club head, the club head comprising:

a body having a face, a sole, a crown and a skirt joining the face, sole and crown, the body having a center of gravity;

the body having a coordinate system with an x-axis located horizontal to the club face, a y-axis located vertical to the club face, and a z-axis located through the club face,

a weight system for the club head,

wherein the center of gravity is adjustable at least along the z-axis and the y-axis.

7. The golf club head of claim 6, the weight system further comprising at least one cartridge for placement within the club head and within a plane formed by the y axis and z axis and wherein said cartridge has a constant density and weight.

8. The golf club head of claim 7, wherein said cartridge is composed of tungsten, aluminum, titanium or a combination thereof.

9. The golf club head of claim 7, wherein said cartridge is exposed through the sole of said club head.
