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.
