If so, SRI may have the solution. Wedge patents don’t come along everyday, and when they do the focus is generally an incredibly complex groove profile. Not this wedge patent; it illustrates a pretty straightforward concept and will probably make you want to give the club a try. The patent is USPN 7,846,033 titled “Iron Type Golf Club Head,” which explains (grind through the awkward translation issues from the original Japanese application):

The present inventor examined the shot made with the face opened. As a result, the present invention was attained based on technical idea different from the conventional one. The present invention found that influence to the hit golf ball in the shot made with the face opened, particularly a backspin speed of the golf ball can be improved. Furthermore, the present invention found that an effect of improving a swing of the golf club in the shot made with the face opened can be obtained.

It is an object of the present invention to provide an iron type golf club head capable of improving a shot made with a face opened.

Admittedly, the translated patent language is extremely hard to read, but I can certainly make-out this part…. “The present invention can improve the swing in the shot made with the face opened. The present invention can improve backspin performance in the shot made with the face opened.” The bottom line for me is that it looks different than all the wedges that have betrayed me in the past, so I would love to give it a try (whether I understand why it is supposed to help me or not).
