The Callaway Bobby Jones putters are designed to give consistent roll and easy set up. Theses putters have traditional designs, with most being flanged blade putters with squared ends and a large footprint. The faces of the Bobby Jones putters are milled for consistent feel and performance and the overall design of the head and shaft helps make sure you're square to your intended line. Some of these putters feature a pocket in the back that improves heel-toe weighting for reduced twisting and also helps visualize the sweet spot, as it is about the size of a golf ball.
