The proximal and distal parts of a golf club shaft that has been cut into two parts are pivotally interconnected to one another and are releasably lockable into any one of a plurality of different positions of angular adjustment by a device having a proximal end and a distal end that are interlockable to one another. The proximal end of the device includes a sleeve that nonreleasably receives the proximal end of the golf club shaft and the distal end of the device includes a sleeve that nonreleasably receives the distal end of the shaft. The device includes a middle part having a first face plate formed by the proximal end of the device and a second face plate formed by the distal end of the device. Radially disposed teeth formed in respective inner surfaces of the first and second face plates enable relative positioning of the face plates in multiple angular relations, and a projection formed on one of the face plates is received within a recess formed adjacent the other face plate and acts as a pointer that indicates a particular setting by pointing at an indicia imprinted adjacent the recess. Successive positions deloft the clubhead face and teach a user how to select irons and how to hold the hands and wrists when chipping and pitching.
