Cutting grooves requires tremendous precision in pursuit of aerospace-grade tolerances. Typical steps include fly-cutting the face, cutting the grooves and applying some form of surface roughness to the flat part of the face between the grooves. The Advanced Research Team scrutinized each of these elements closely in search of ways to improve them. A great deal of discussion and debate led the group to agree that the process of rendering a groove could be more precise and consistent from one end of the groove to the other, and from one groove to another. That led them to develop a new, proprietary saw-cutter only Callaway has, with eight saw-blades oriented to mill the groove horizontally for a tremendously precise process. The wall-angle of each groove was increased to an ultra-sharp 5° in wedges 54° loft and above (20° in pitching and gap wedges). The 5° angle promotes more spin and control, especially out of the rough, in wet conditions, and around the green.
