GOLF CLUB HAVING REMOVABLE SOLE WEIGHT
First Claim
1. A golf club head comprising a hosel, face, crown, skirt, and sole,wherein the sole comprises at least a first removable weight member,wherein at least a portion of said first removable weight member has a basis weight greater than that of the sole, and the first removable weight member comprises a non-threaded attachment mechanism, andwherein said first removable weight member has a chip ratio, defined as the plan area of the first removable weight member divided by the effective thickness of the first removable weight member, of greater than about 8,wherein the plan area is a maximum amount of two-dimensional surface that can be projected on to a plane defined by a longitudinal axis and width axis of the first removable weight member and the effective thickness is the volume of the first removable weight member divided by the plan area.

Abstract
A golf club head is presented comprising a sole including a removable weight member secured to the sole via a non-threaded attachment assembly. Further, the removable weight member has a large surface area relative to its thickness, resulting in a chip-like or wafer-like weight member. This design allows the mass of the weight member to be spread substantially along the surface of the sole as opposed to in the interior of the club head. The golf club head may comprise more than one removable weight member. A weight member of the present invention may comprise one or more discrete areas of higher basis weight or higher density.

18. A golf club head comprising a hosel, face, crown, skirt, and sole,
wherein the sole comprises at least a removable weight member, wherein said removable weight member has a non-threaded attachment mechanism and defines at least one cavity sized and dimensioned to receive an insert with a density greater than that of the removable weight member and wherein said removable weight member has a chip ratio, defined as the plan area of the removable weight member divided by the effective thickness of the removable weight member, of greater than about 8, wherein the plan area is a maximum amount of two-dimensional surface that can be projected on to a plane defined by a longitudinal axis and width axis of the removable weight member and the effective thickness if the volume of the removable weight member divided by the plan area.
