Technology That Has Stood The Test Of Time
The development of the Short, Straight, Hollow, Hosel in 1988 is one of Callaway Golf’s key technological breakthroughs. This patented Callaway Golf design shortened the length of the hosel, allowing weight to be moved lower and to the more useful perimeter area of the clubhead.

The hollowed-out or Modified Tru-Bore Technology is part of the S2H2 Design, and allows the shaft tip to extend through the hosel and clubhead to the sole. This bore-through design improves feel and control by moving the tip of the shaft closer to the center of the clubface.
