Abstract
In a set of correlated golf clubs, the heads are provided with a narrowed neck (36) connecting the main body (32) of the club head to the hosel (34). A midsection (46) of the neck has a cross section of maximum dimension less than the diameter of the hosel so that, when the main body of the club head twists under impact with a ball, the narrowed neck will function as a torsion bar with most of the torsion occurring in the midsection (46). In that manner, the twisting motion of the main body is uncoupled from the hosel and shaft.
