- (i) a tip end for attaching a club head to said shaft,
- (ii) a butt end for attaching a grip to said shaft,
- (iii) a circular cross section, and
- (iv) marking means for discerning increments of angular rotation within the range from 1.degree. to 15.degree. of said shaft from alignment in a predetermined position, said means comprising linearly extending marking indicia on either or both of the lateral external surfaces of said shaft relative to a top dead center surface position on said shaft and extending up said shaft away from said tip end for a distance sufficient to allow a golfer to view said marking means from said butt end along at least a portion of the shaft distance between said tip end and a point midway between said tip end and said butt end; and
- (b) a golf club head attached to said tip end.

- 5. A club as in claim 1 wherein said means for discerning increments of angular rotation on said shaft comprises at least two line spaced apart from each other.
- 6. A club as in claim 5 wherein said at least two lines are visible on said shaft within an angle, .alpha., of 45.degree. to 135.degree. from a clockwise position relative to top dead center of said shaft.
- 7. A club as in claim 5 wherein said at least two lines are visible on said shaft within an angle, .beta., from 225.degree. to 315.degree. relative to top dead center of said shaft.
- 8. A club as in claim 5 wherein the lines exhibit a width within the range from 5 to 75 thousandths of an inch.
- 9. A club as in claim 1 wherein said means for discerning increments of angular rotation on said shaft comprises: (a) at least two lines spaced apart from each other within an angle, .alpha., of 45.degree. to 135.degree. from clockwise position relative to top dead center of said shaft; and (b) at least two lines spaced apart from each other within an angle, .beta., from 225.degree. to 315.degree. relative to top dead center of said shaft.
- 10. A club as in claim 1 wherein said means for discerning increments of angular rotation on said shaft further comprises a linearly extending marking indicia along said top dead center position at said tip end.
- 11. The club of claim 1 wherein said shaft exhibits a taper in diameter from said butt end to said tip end.
