First Claim
1. A golf club head comprising:
- a face having a ball striking surface and being defined by a peripheral edge;
a body connected to the face and extending rearward from the face to define an enclosed volume, the body having a front side, a rear side, a heel side, a toe side, a crown, and a sole;
a first channel located on a surface of the body, the first channel having a periphery defined by boundary edges, wherein the boundary edges include a front edge extending laterally along the peripheral edge of the face between a heel end and a toe end of the first channel, such that the heel end and the toe end are located on opposite sides of a geometric centerline of the body, and the boundary edges further include a rear edge located further rearwardly than the front edge, wherein the first channel extends from the front edge to the rear edge, and the first channel has a width measured in a front-to-rear direction between the front and rear edges,wherein the rear edge includes a heel portion extending forward to the front edge and toward the heel side of the body at a first angle to the front edge, such that the first channel tapers to a first point formed by the heel portion and the front edge at the heel end of the first channel, and the rear edge further includes a toe portion extending toward the front edge and toward the toe side of the body at a second angle to the front edge, such that the first channel tapers to a second point formed by the toe portion and the front edge at the toe end of the first channel.

Abstract
A ball striking device, such as a golf club head, includes a face having a ball striking surface configured for striking a ball and a body connected to the face and extending rearwardly from the face. The body has an impact-influencing structure in the form of a channel positioned on at least one surface of the body. A majority of a force generated by impact with a ball is absorbed by the impact-influencing structure, and a majority of a response force generated by the head upon impact with the ball is generated by the impact-influencing structure. The face may have increased stiffness as compared to existing faces, and may include a stiffening structure to create the increased stiffness, such as a porous or cellular stiffening structure.
