Looks like belt buckles are the new big thing on the PGA tour.  Specifically buckles made by Bob Bettinardi.  Bettinardi is know for his hand crafted putters but more an more golfers are now coming to him for custom belt buckles.  Angel Cabrera wore one at the Masters two weeks ago.  Other customers include Sergio Garcia (who ha been wearing them for a long time), Padraig Harrington and Kevin Streelman, who has an endorsement deal with Bettinardi.

While Bettinardi makes some nice looking buckles, none of them will match the awesomeness of the buckles worn by Rory Sabatini.
