The Yes! Callie-F is a blade putter with a plumber’s neck hosel and is a good option for players with a slight arc swing path. The Callie-F is made of 304 stainless steel weighing 355 grams with a slight toe-hang so the head stays square through impact for players with an arced putting stroke. The offset hosel helps frame the ball at address for more confident strokes and the C-groove technology from Yes! helps get the ball rolling sooner for more consistently smooth putts.
