Abstract

A golf putter head with a front portion comprising traditional shape and appearance, with an integral face insert extending through the head to an alignment and weighting portion extending beyond the main body of the putter, adding improved alignment, increased moment of inertia (MOI) and adjustable weighting and adjustable balance and optimizable center of percussion. The putter head comprises a central face insert portion extending through the body and above the traditional weight flange, with mass relieved portions below the top of the alignment piece in order to receive one or more optional weights, and the upper side of the rearwardly extending portion being engraved or marked with various alignment indicia, and the whole through-head insert face portion and rearwardly extending portion being affixed to the base portion of the head at least in part with threaded fasteners.

Claims

1. A golf club head assembly, comprising, in combination:

a first discrete, interchangeable weight portion;

a second discrete, interchangeable weight portion having a different weight profile as compared to the first interchangeable weight portion;

a face with milled grooves therein;

a hosel;

a body adapted to receive and retain accessibly and detachably one of;

the first interchangeable weight portion, and the second interchangeable weight portion; and

the first interchangeable weight portion when received and retained accessibly and detachably in the body presenting a first center of gravity relative to the body to which it is received and retained accessibly and detachably;

the second interchangeable weight portion when received and retained accessibly and detachably in the body presenting a second center of gravity relative to the body to which it is received and retained accessibly and detachably, the second center of gravity different from the first center of gravity;

where the shaft alignment configuration of the hosel and a weight configuration provided by the received and retained interchangeable weight portion alters a balance of the golf club head.

2. The golf club head assembly as described in claim 1 wherein the hosel is a modular hosel either integrated with or connected to the head and having one of different shaft alignment configurations coupled to the body.
