<p>In a set of correlated golf clubs, the heads 30 are provided with a narrow neck 36 connecting a main body 32 of the club head to its hosel 34. A midsection 46 of the neck 36 has a cross section of maximum dimension less than the diameter of the hose 34 so that, when the main body 32 of the club head 30 twists under impact with a ball, the narrow neck 36 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 32 is uncoupled from the hosel 34 and shaft. <IMAGE></p> |
