Open the CIPO recordAbstract From the Canadian patent
In a set of correlated golf clubs the heads are pro-, vided 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 nar-, rowed 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.
