Abstract

A ball striking device, such as a golf club, includes a head with a face having an outer surface configured for striking a ball, a body connected to the face, an elongated, inwardly recessed channel located on the body and extending across a portion of the body, and an insert mounted within the channel. The insert includes a resiliently deflectable base member that engages the channel to retain the insert within the channel and a rigid outer member connected to the base member and forming at least a portion of the outer surface of the insert, where the outer member is made from a different material than the base member. Additionally, the insert has an outer surface that is substantially flush with at least one immediately adjacent surface of the body.
