Abstract

A ball striking device, such as an iron-type golf club head, includes a face having a ball striking surface defined thereon and a body connected to the face. The body has a sole member extending rearward from a bottom edge of the face, and the sole member has a sole surface configured to confront the playing surface. The head has an elongated channel located in the sole member, and the channel is recessed from the sole surface, extends along at least a portion of the bottom edge of the face and is spaced from the bottom edge.

17. The head of claim 11, wherein at least one of the side walls of the channel is parallel to the face when viewed in cross-section.

18. An iron-type golf club comprising the head of claim 11 and a shaft connected to the head.

19. A head for an iron-type golf club, comprising:

a face having a ball striking surface configured for striking a ball;

an iron-type body connected to the face, the body comprising a plurality of peripheral walls extending rearward from outer edges of the face, the peripheral walls including a sole member extending rearward from a bottom edge of the face, the sole member having a sole surface configured to confront a playing surface;

an elongated channel located in the sole member, the channel being defined by a first end located on the sole surface, a second end located on the sole surface, and two edges extending across the sole surface between the first and second ends, the channel having a length defined between the first and second ends, and the channel comprising a trough that is recessed from the sole surface and two opposed side walls extending from the trough to the edges of the channel, wherein the channel is spaced rearwardly from the bottom edge of the face and the edges of the channel are generally parallel to the bottom edge; and

a flexible insert connected to the body and mounted within the channel, wherein the insert has a length that is shorter than the length of the channel, such that opposed ends of the insert are spaced from the first and second ends of the channel.

20. The head of claim 19, wherein the channel has a depth of recession from the sole surface, and wherein the depth of the channel is tapered, such that the depth of the channel is greater at a center of the channel than at opposed ends of the channel.
