A ball striking device, such as a golf club, includes a head with a face having a ball-striking surface configured for striking a ball, a body connected to the face, and at least one channel in the ball-striking surface of the face. The region of highest COR response of the face is directionally enlarged toward the channel. Depending on the size, shape, and location of the channel, the face can be altered to provide greater COR response and increased energy transfer for impacts at specific locations on the face.

Golf club head or other ball striking device having one or more face channels

In general, aspects of this invention relate to blade-type iron golf clubs or golf club heads. The blade-type golf club head may comprise a body forged of a metal material. The body may include a hosel, a top surface, a sole, a heel, a toe, a ball striking surface, and a rear surface opposite the ball striking surface. The rear surface may have an upper blade portion and a lower muscle portion with the upper blade portion separated from the lower muscle portion by a blade interface. The lower muscle portion may have a muscle portion surface are that includes a heel muscle surface area measured from the ball striking centerline to the heel and a toe muscle surface area measured from the ball striking centerline to the toe. The toe muscle surface area may make up at least 60% of the muscle portion surface area. The mass distribution of the lower muscle portion moves the center of gravity of the club head closer to the face center location.

Iron-type golf clubs and golf club heads

A golf club head having a metal portion adhered to a non-metal portion to define a closed internal volume therebetween, and an elongated channel extending across a portion of the sole. The channel may be recessed from 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 of the center portion of the channel is substantially constant, and wherein the width of the channel increases from the heel end of the center portion to the heel and from the toe end of the center portion to the toe.

Golf club head or other ball striking device having impact-influencing body features

A golf club includes a shaft and a club head. The club head includes a body member having a ball striking face, a heel, a toe, a back, a crown, a sole, and a hosel region located at the intersection of the ball striking face, the heel and the crown. The sole includes a channel extending from the hosel region toward the toe. An insert is received within the channel. The club head further includes means for detachably securing the insert to the channel. A second insert configured for being received within the channel may be provided.

Golf club assembly and golf club with aerodynamic features

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.

A golf club head includes a body member having a ball striking face, a crown, a toe, a heel, a sole, a back and a hosel region, located at the intersection of the ball striking face, the heel, the crown and the sole. The body member may have a first cross-section having a first airfoil-shaped surface in the heel. The first cross-section may be oriented at approximately 90&#xb0; from the centerline of the club head. The body member may have a second cross-section having a second airfoil-shaped surface. The second cross-section may be oriented at approximately 45&#xb0; or at approximately 70&#xb0;. The airfoil-shaped surfaces may be defined by spline points or by equations. A golf club including the golf club head is also provided.

Golf club head

Golf club head for a putter

A golf club includes a shaft and a club head. The club head may have a channel extending adjacent to a trailing edge of the club head. The channel may have a maximum depth of 6 mm and a maximum width ranging from 10 mm to 20 mm. A rough textured surface region may be provided on a sole, wherein the rough textured surface region has a surface roughness of greater than or equal to 1.00 &#x3bc;m. A recess, formed in the sole, may extend from a mid-region to a toe of the club head, wherein the mid-region extends over the middle 40% of a length of the club head. A crown has an upper, forward surface and a stepped-down region, and the upper, forward surface transitions to the stepped-down region at a transition feature that extends from the hosel region at an angle of from 25 to 50 degrees.
