Vertical Groove

Score lines or grooves on golf club faces that run vertically from top to bottom of the face, perpendicular to the traditional horizontal groove pattern. Vertical grooves are less common in modern club design but have been used in some specialty wedges and putters to provide different spin and ball interaction characteristics. The orientation and spacing of grooves significantly affects ball spin and control, with regulations governing groove dimensions and patterns. Most modern clubs feature traditional horizontal grooves due to their proven effectiveness in generating appropriate spin rates.
