<p>PURPOSE: To make possible to conduct an accurate direction matching of hitting face of a club, by containing a member to form an aligning line extending on a vertical face for a plane of a hitting face. CONSTITUTION: A hitting face has a heel 15 and a toe end 16 mounted at proximity of a shaft 11. In general, a patter has a curved bottom 20. As an upper side 25 of the head can be made to a desired shape, it has another part of the upper face 25 and a long and narrow place 26, one of reference rib 27 divided on vision from another part. A face 26 is vertical to the hitting face 13. The faces 26, 27 are inclined upwards from rear side to front side of the club. The face 26 is typically somewhat long and narrow, and nearly a perfect line, so this face 26 is called a line 26 namely an aligning line. By using the reference line vertical to the hitting face 13, a golfer can be obtained any angle relation between the club and lawn grass as long as leading the reference line to a correct direction.</p> |
