Abstract
A ball striking device, such as a golf club head, has a head that includes a face configured for striking a ball and a body connected to the face, the body being adapted for connection of a shaft proximate a heel thereof. The face has a thickened portion including an annular tapered area that tapers in thickness between an upper boundary and a lower boundary and encloses an elevated area bounded by the upper boundary. The upper and/or lower boundary defines a shape having two lobes, each with an outer edge with a convex profile, and a connecting portion extending between the lobes, such that the connecting portion is defined by two outer edges extending between the outer edges of the lobes, wherein at least one of the outer edges of the connecting portion has a concave outer profile.
