Claim 0:
1. A golf club head comprising:
a forged body portion;
a first cavity, having a first cavity thickness measured perpendicular to a face plane of a striking face insert, defined within a blade portion of said body portion;
a second cavity, having a second cavity thickness measured perpendicular to said face plane of said striking face insert, defined within a muscle portion of said body portion;
a rib at least partially separating said first cavity and said second cavity; and
said striking face insert further comprising:
a first portion, having a first face thickness measured perpendicular to said face plane of said striking face insert, engaged with said first cavity;
a second portion, having a second face thickness measured perpendicular to said face plane of said striking face insert, engaged with said second cavity; and
a transition portion, having a variable thickness measured perpendicular to said face plane of said striking face insert, separating said first portion and said second portion,

wherein said second face thickness is greater than said first face thickness,
wherein a ratio of said first face thickness to said first cavity thickness is between about 0.2 and about 4.0,
wherein a ratio of said second face thickness to said second cavity thickness is between about 0.1 and about 0.8,
wherein said golf club head further comprises a rod extending from within said first cavity toward a front of said golf club head,
wherein said striking face insert includes a hole located proximate to said rod,
wherein said rod has a rod diameter,
wherein said hole has a hole diameter,
wherein said rod diameter is between about 10% and about 100% greater than said hole diameter, and
wherein said striking face insert is welded to said body portion around a perimeter of said striking face insert and welded through said hole to said rod to define a rosette weld.
