1. A golf club head comprising:
- a club head body member made of a first material comprising a heel, a toe, a portion of a crown, a portion of a sole;
a face member made of a second material comprising a central portion of the striking face and a portion of the crown adjacent to the striking face; and
an elongated channel extending across a portion of the sole in a heel-to-toe direction, wherein the elongated channel is recessed from adjacent surfaces of the sole and has a plurality of side walls and a depth of recession from the adjacent surfaces of the sole,wherein the sole comprises a plurality of materials with the elongated channel and the adjacent surfaces comprising a third material and a fourth material and the remainder of the sole comprising the first material,wherein the adjacent surfaces of the elongated channel and a portion of the side walls of the elongated channel are made of the third material and the remainder of the elongated channel is made of the fourth material.

Abstract
A ball striking device, such as a golf club head, has a face with a striking surface configured for striking a ball; an elongated channel extending across a portion of the sole, wherein the sole the sole has an elongated channel recessed from adjacent surfaces. The elongated channel is made of a plurality of materials such that the materials making up the elongated channel have a lower modulus of elasticity than the modulus of elasticity of the material remainder of the sole. The lower modulus materials help to control the flexibility of the elongated channel, which can improve the efficiency of the impact with a golf ball.
