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 adjacent surfaces of the sole and have 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, wherein the width and the depth of the center portion of the channel are substantially constant, and wherein the depth of the channel is greater at the heel and toe portions 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 directi
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 variable depth of recession from the adjacent surfaces of the sole, wherein the channel comprises a center portion having a curved and generally semi-circular cross-sectional shape and parallel to the face 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,wherein the channel has a front edge, a rear edge, and a width defined between the front and rear edges, wherein the width and the depth of the center portion of the channel are substantially constant, andwherein the depth of the channel is variable over a length of the channel and is greater at the heel and toe portions than at the center portion, such that the depth 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, and further wherein an access for a hosel connecting structure is in communication with and intersects the heel portion of the channel. 2. The golf club head of claim 1, wherein the front and rear edges of the channel are angled away from each other at the heel portion and the toe portion and further wherein the width of the channel at the heel and toe portions is greater than the width of the channel at the center portion. 3. The golf club head of claim 1, wherein the front and rear edges of the channel are angled away from each other at the heel portion and the toe portion and further wherein the width of the channel is smaller at the heel and toe portions than at the center portion. 4. The golf club head of claim 1, further comprising a void defined on the sole of the body, wherein the body comprises a first leg and a second leg extending rearwardly from a base portion of the body, with the void being defined between the first and second legs, and a cover extending between the first and second legs and defining a top of the void. 5. 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. 6. 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;a channel extending across a portion of the sole, wherein the channel is recessed from adjacent surfaces of the sole and has a variable depth of recession from the adjacent surfaces of the sole, wherein the channel comprises a center portion having a curved and generally semi-circular cross-sectional shape and parallel to the face 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, wherein the depth of recession of the channel is variable over a length of the channel and is greater at the heel and toe portions than at the center portion such that the depth of recession 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, and further wherein an access for a hosel connecting structure is in communication with and intersects the heel portion of the channel;a void defined on the sole of the body and a cover defining a top of the void; andwherein the body and the face combine to define an internal cavity, with a top 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. 7. The golf club head of claim 6, wherein the channel has a width defined in a front to rear direction. 8. The golf club head of claim 7, wherein both the width and the depth of the channel are greater at the heel portion and the toe portion than at the center portion. 9. The golf club head of claim 6, wherein the void is not visible from an address position of the golf club. 10. The golf club head of claim 6, further comprising a pair of external ribs connected to the cover and extending downward from the cover, such that the external ribs are positioned within the void. 11. 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, the channel having a width defined in a front to rear direction and a variable depth of recession from the adjacent surfaces of the sole, wherein the channel comprises a center portion having a curved and generally semi-circular cross-sectional shape and parallel to the face 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 wherein the depth of recession of the channel is variable over a length of the channel such that the depth 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 and at least one of the width and the depth of the channel is greater at the heel portion and the toe portion than at the center portion, and further wherein an access for a hosel connecting structure is in communication with and intersects the heel portion of the channel; anda void defined on the sole of the body, wherein the body comprises a first leg and a second leg extending rearwardly from a base portion of the body, with the void being defined between the first and second legs. 12. The golf club head of claim 11, wherein both the width and the depth of the channel are greater at the heel portion and the toe portion than at the center portion. 13. The golf club head of claim 11, wherein the void is not visible from an address position of the golf club. 14. The golf club head of claim 11, further comprising a cover extending between the first and second legs and defining a top of the void. 15. The golf club head of claim 14, further comprising a pair of external ribs connected to the cover and extending downward from the cover, such that the external ribs are positioned within the void. 16. The golf club head of claim 14, wherein the body and the face combine to define an internal cavity, with a top 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. 17. The golf club head of claim 11, 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.
