Rife Island Series Barbados Heel Shafted Putter Rife Putters with RollGroove Technology, utilize less loft because of the friction or gripping created by the grooves on the face. The ball is gripped rather than chipped, held through impact, and then released into an immediate forward roll. The Two Bar Putter allows the individual golfer to self adjust his or her putter shaft lie angle to lock in a consistent address position. Setting up to the ball the same way each time promotes a repeatable stroke path and greater accuracy
