A groove configuration for a putter type golf club head formed of a series of grooves. Each groove has a first surface disposed at an angle no greater than 90 degrees to the ball striking face and a second surface disposed at a lesser angle to the ball striking face. The outermost edges of the groove surfaces intersect in a saw-tooth configuration to provide a gripping area which imparts spin to a golf ball when it is struck by the putter type golf club.
