1. An adjustable loft golf club comprising:
- (a) a shaft having a frustoconical-shaped spline at a lower end thereof, said spline having a first central axis and comprising a plurality of circumferentially spaced first teeth which taper inwardly toward said first central axis;
(b) a blade having a recessed socket at a heel end thereof for matingly receiving said spline, wherein said socket comprises a second central axis and a plurality of circumferentially spaced second teeth which taper outwardly in a direction away from said second central axis; and
(c) fastening means for releasably coupling said blade and said shaft together when said first and second central axes are aligned such that said first teeth lockably inter-engage with said second teeth to maintain said blade at a selected angular position relative to said shaft.
