Iron golf club with round sole

摘要

An iron golf club includes a sole with a bulger round 16, i.e. a convex curvature in the fore and aft section. The bulger round is formed by a curved surface having a radius of curvature R1 smaller than 20 millimeters between the leading edge and the trailing edge. The curve may be simple as shown or may have sections radiused about two distinct centres of curvature.
