Abstract
A ball striking device, such as a golf club head, has a face with a striking surface configured for striking a ball and a channel extending across a portion of the sole. The channel may be recessed from the sole and have a depth, wherein the channel comprises a center portion extending across a center of the sole, a heel portion extending from a heel end of the center portion toward the heel, and a toe portion extending from a toe end of the center portion toward the toe. The channel may have a width defined between a front edge and a rear edge, and a cross-sectional shape, wherein the cross-sectional shape of the center portion of the channel is substantially semi-circular, and wherein the cross-sectional shape of the channel is different at the heel and toe portions than at the center portion.
