lift line zll parallel to the hosel z axis to eliminate out of swing plane forces and to minimize lift induced drag orienting the hosel 20 airfoil cross section in this manner will place the chord line at an angle to the target line at address this may appear abnormal to the golfer but using a reflex trailing edge may be helpful in eliminating this appearance while having minimal effect on the aerodynamic performance of the section with certain airfoils it is likely that airflow will be separated over the aft portions of the airfoils at low reynolds numbers typical of a golf swing one approach to delaying separation is creating a multi element or slotted airfoil a three element 21 23 25 version of such a hosel 20 having two slots 21 a 23 a is shown in fig1 the hosel 20 shown in fig1 is cambered and has a 30 thick cross section but may have other thickness percentages two element versions which can be obtained by filling in either of the slots 21 a 23 a in the hosel 20 shown in fig1 are also viable configurations this multi element or slotted configuration can be further generalized to include many slots and elements this multi element or slotted configuration may further comprise the entire length of the hosel 20 or be included as an aerodynamic hosel portion another approach shown in fig1 involves truncating the trailing edge 28 portion of the airfoil hosel 20 c this helps to reduce the blockage effect and resulting drag at high flow angles early in the swing the mass of the hosel and the resulting impact on head center of gravity is also reduced by this.
