International ClassA63B 053/02AbstractA wood head golf club is described in which the usual hosel is eliminated and provision is made for anchoring the graphite or other shaft within the club head within a rigid sleeve positioned therein, thus eliminating the objectional degree of rigidity imparted by the use of a hosel which extends beyond the clubhead. As a result a greater degree of flex and torque is obtainable from the shaft. The sleeve is preferably formed with an outwardly tapering shoulder which provides a space for cushioning material between shaft and shoulder. | |
