Having Trouble Getting Enough Spin on Your Wedge Shots?
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 
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).
