Iron-type golf club head or other ball striking device

An iron-type golf club head comprising:

• a face having a substantially flat ball-striking surface at a front of the golf club head configured for striking a ball;
• an iron-type body connected to the face, the body having a sole surface configured to confront a playing surface in use;
• wherein the head is formed in part by a face member having a first leg forming at least a major portion of the face and a second leg extending rearwardly from a bottom end of the first leg and forming at least a portion of the sole surface, and the head is further formed in part by a body member connected to the face member, the body member having a top portion forming at least a portion of a top side of the body and a top section of the ball-striking surface, and a bottom portion forming at least a portion of the sole surface;
• wherein a juncture is formed between the face member and the body member, the juncture extending across the top section of the ball-striking surface, between a top end of the first leg and the top portion of the body member, downward along a heel side and a toe side of the body, and across the sole surface of the body, between a rear end of the second leg and the bottom portion of the body member;
• wherein the body further comprises a sole member having the sole surface thereon and a rear cavity defined at least partially by the sole member and a rear surface of the face, wherein a bottom surface of the cavity is defined by portions of the body member and the face member;
• a connection structure connecting the face member to the body member to form the head, wherein the connection structure comprises a plurality of weld line segments along the juncture, wherein the plurality of weld line segments are intermittent and extend over less than the entire juncture;
• wherein the body has an elongated, recessed channel extending within the cavity along a junction line between the rear surface of the face and the sole member;
• and
• wherein a difference in height is defined between the rear end of the second leg and a front end of the bottom portion, such that the channel is created by the difference in height, and the channel is recessed with respect to a top surface of the front end of the bottom portion.
