Putter Head, Nike Inc.

Back to Nike again (they have a suprising number of patents). This time its the lucrative golf market. In their preamble Nike talks about how important the 'feel' of a golf club, especially the putter, is to a player and how this feel varies from person to person. To combat this problem they have designed a putter with an 'adjustable, multi-sided ball striking face insert'. 

Several configurations, including triangular, square and hexagonal cross section inserts are shown. The striking face is changed by separating the putter head as seen below.

This patent was filed July 27th 2010 but not approved until Jan 15th 2013. Will we see it in the hands of Tiger or Rory McIlroy this year? Looks a bit flimsy to me. 

Is this a moneymaking gimmick for the golfing dad who has everything?
