SB stands for “snake bite,” and in that spirit the grooves are designed with sharper angles and curves so that the edges can more easily “bite” into the ball’s cover for more backspin. The clubface’s cross-sectional groove area is larger than past Cobra wedges to allow the club to perform better out of the rough and to repel water and grass in wet conditions. Three distinct features help increase spin throughout the wedge set: a variable-thickness pattern between the grooves, a unique surface that fosters more spin on shorter wedge shots and a progressive groove design—deep, narrow grooves on the lower lofts and shallow, wide grooves on the higher lofts. Available in three grinds, seven lofts and in One Length, which has been engineered to perform at a 7-iron length and swingweight.
