Abstract
A multiple-material golf club head with an improved scarf joint between the crown and the body, and a method of finishing said golf club head is disclosed herein. The golf club preferably has a metal body comprising a striking face, a sole, a return portion, a bond flange, and a rear flange, and a composite crown having a scarf region, a step portion, and a constant thickness region directly behind the scarf region. The golf club is manufactured by providing a club head with a bond flange, providing a composite crown with a scarf region delineated by a front edge and a step portion and/or groove, bonding the scarf region to the bond flange to form an upper golf club head surface, and grinding the upper golf club head surface only from a location proximate the front edge to a location proximate the step portion and/or groove.
