A ball striking device, such as a golf club head, has a face with a striking surface configured for striking a ball; a channel extending across a portion of the sole, wherein the channel is recessed from adjacent surfaces of the sole; a void defined on the sole of the body and a cover defining a top of the void; and a first external rib and a second external rib wherein each external rib is connected to the cover and extends downward from the cover, such that the external ribs are positioned within the void. The channel has a width and a depth, wherein the channel comprises a center portion, a heel portion, and a toe portion, and wherein at least one or both of the width and the depth of the channel is greater at the heel portion and the toe portion than at the center portion.
1. A golf club head comprising: a face having a striking surface configured for striking a ball; a body connected to the face and extending rearwardly from the face, the body having a crown, a sole, a heel, and a toe; an elongated channel extending across a portion of the sole in a heel to toe direc
1. A golf club head comprising: a face having a striking surface configured for striking a ball; a body connected to the face and extending rearwardly from the face, the body having a crown, a sole, a heel, and a toe; an elongated channel extending across a portion of the sole in a heel to toe direction, wherein the channel is recessed from adjacent surfaces of the sole and has a depth of recession from the adjacent surfaces of the sole, 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; a void defined on the sole of the body and a cover defining a top of the void; and at least one external rib is connected to the cover and extending downward from the cover, such that the at least one rib is positioned within the void, wherein the channel has a front edge, a rear edge, and a width defined between the front and rear edges, wherein the width of the center portion of the channel is substantially constant, and wherein the front and rear edges of the channel are angled away from each other at the heel portion and the toe portion, such that the width of the channel at the heel and toe portions increases from the heel end of the center portion toward the heel and from the toe end of the center portion toward the toe, wherein the depth of the channel is greater at the heel and toe portions than at the center portion, and further wherein the at least one external rib further comprises an upper portion, a lower portion, a front portion, a back portion, and a central portion, wherein the lower portion has a width that is greater than the width of the central portion of the rib. 2. The golf club head of claim 1, wherein the at least one external rib comprises a pair of external ribs. 3. The golf club head of claim 1, further comprising at least one internal rib connected to an internal portion of the body and extending into the internal cavity. 4. The golf club head of claim 3, wherein the at least one internal rib comprises at least one upper internal rib connected to an internal portion of the cover and connected to an internal portion of the crown. 5. The golf club head of claim 3, wherein the at least one internal rib comprises at least one lower internal rib connected to an internal portion of the sole and connected to an internal portion of the channel. 6. The golf club head of claim 3, wherein the at least one internal rib comprises at least one lower internal rib connected to an internal portion of the sole and connected to an internal portion of the cover. 7. The golf club head of claim 1, wherein the channel has a wall thickness that is greater in the center portion of the channel than in at least one of the heel and toe portions. 8. A golf club head comprising: a face having a striking surface configured for striking a ball; a body connected to the face and extending rearwardly from the face, the body having a crown, a sole, a heel, and a toe; an elongated channel extending across a portion of the sole in a heel to toe direction, wherein the channel is recessed from adjacent surfaces of the sole and has a depth of recession from the adjacent surfaces of the sole, 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; and a void defined on the sole of the body and a cover defining a top of the void; and a first external rib and a second external rib wherein each external rib is connected to the cover and extends downward from the cover, such that the external ribs are positioned within the void, wherein each of the external ribs further comprise an upper portion, a lower portion, a front portion, a rear portion, and a central portion, wherein the channel has a front edge, a rear edge, and a width defined between the front and rear edges, wherein the width of the center portion of the channel is substantially constant, and wherein the front and rear edges of the channel are angled away from each other at the heel portion and the toe portion, such that the width of the channel at the heel and toe portions increases from the heel end of the center portion toward the heel and from the toe end of the center portion toward the toe, wherein the depth of the channel is greater at the heel and toe portions than at the center portion, and further wherein the body and the face combine to define an internal cavity, with a to surface of the cover partially defining the internal cavity, such that a portion of the internal cavity is positioned between the cover and the crown. 9. The golf club head of claim 8, wherein the pair of external ribs diverge away from one another in a rear to front direction. 10. The golf club head of claim 8, wherein the lower portion of the first external rib has a first width and the central portion of the first external rib has a second width, wherein the first width is greater than the second the central portion. 11. The golf club head of claim 10, wherein the lower portion of the second external rib has a third width and the central portion of the second external rib has a fourth width, wherein the first width and the third width are substantially similar and wherein the second width and the fourth width are substantially similar. 12. The golf club head of claim 8 further comprising at least one internal rib connected to an internal portion of the body and extending into the internal cavity. 13. The golf club head of claim 12, wherein the at least one internal rib comprises at least one upper internal rib connected to an internal portion of the cover and connected to an internal portion of the crown. 14. The golf club head of claim 12, wherein the at least one internal rib comprises at least one lower internal rib connected to an internal portion of the sole and connected to an internal portion of the channel. 15. The golf club head of claim 12, wherein the at least one internal rib comprises at least one lower internal rib connected to an internal portion of the sole and connected to an internal portion of the cover.
