Already famed as Drew Gibson's putter-only sponsor, EV-7 is a new company founded in July 2020 by Phil Arthur. Phil is a former PDGA Hall of Fame National Tour Champion, 2009 Masters World Champion, and co-founder of Prodigy Disc. The Penrose is EV-7's debut putt and approach disc. “This putter is weighted differently that a normal putter,” said Gibson of the Penrose. “It’s a masterpiece. It’s designed different than a standard putter. You can feel the difference right away when you pick it up.”
