I have a Vokey SM4 52.08* gap wedge in Oil Can finish. I purchased this wedge late this past summer, and have been using it since. I am quite an avid golfer, so I would definitely say I've taken well over 1,000 swings with it. As I was inspecting the grooves today, I saw that the surface roughness around the bottom of the club face and on the sweet spot are almost completely worn smooth. Of course, the top of the club face where there is virtually no contact with the ground or ball looks brand new. Is this common? And will it affect the performance of the club? I know a lot of people have Vokey wedges that they've used for years, so I'm assuming it's not a big deal. Just curious.
