Abstract: 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.

Abstract: Golf clubs and golf club heads, such as putter heads (102), may include a putter body and an adjustable ball striking face insert (116) forming at least a portion of the ball striking face (104) and contained within the putter body. The insert (116) may have a plurality of sides (118a, 118b, 118c, 118d), each of the sides having different performance characteristics to permit customization of the putter (100). In some examples, the adjustable ball striking face insert (116) may be rotatably mounted within the putter head. Additionally or alternatively, the insert (116) may be removably mounted within the putter head (102). In some arrangements, the insert (116) may be finely adjustable to alter the loft angle of the putter head (102).
