1. A putter head comprising:
- (a) an elongated element having a vertical plane of symmetry, said elongated element comprising;
(i) two laterally spaced masses, each of said two laterally spaced masses comprising a shape having an increasing dimension with respect to a direction normal to and away from said vertical plane of symmetry and a predetermined density;
(ii) a linking portion extending between said two laterally spaced masses; and
(iii) a generally planar front surface constituting a golf ball striking surface;
(b) a shell adapted to have a shaft extending therefrom, said shell having a front portion, said front portion of said shell having an opening for receiving and seating said elongated element, while leaving said generally planar front surface exposed, said shell comprising a material having a density lower than said predetermined density of either of said masses, wherein said masses provide an increased moment of inertia for said elongated element so as to prevent undesirable rotation of the putter head at the moment of contact with a golf ball; and
(c) means for affixing said elongated element to said shell comprising means for directly securing at least one of (i) said laterally spaced masses and (ii) said linking portion to said shell.

Abstract
A golf club, particularly a putter, having a head which includes an elongated element affixed to a shell and a method of assembling the golf club. The elongated element includes two laterally spaced masses, a linking portion extending between the two laterally spaced masses and a generally planar front surface constituting a golf ball striking surface. The shell, which is adapted to have a shaft extending therefrom, includes a front portion having an opening for receiving and seating the elongated element, while leaving the generally planar front surface exposed.
