1. A golf club head comprising:
- a face having an outer surface configured for striking a ball;
a body connected to the face and extending rearward from the face, the body including a top side, a sole configured to confront a playing surface in use, and an outer periphery including a heel side, a toe side, and a rear opposite the face; and
an inwardly recessed channel at least partially located on the sole of the body and being configured to influence the impact of a ball on the face, the channel comprising a first portion having a distal end located proximate the outer periphery and extending toward a center of the sole from the distal end, wherein the first portion of the channel is elongated and is defined by a boundary edge that includes a front edge that is generally parallel to at least one peripheral edge of the face and a rear edge positioned rearwardly of the front edge,wherein the channel further comprises a second portion extending away from the distal end of the first portion toward the rear and away from the face, in a direction transverse to a direction of elongation of the first portion, andwherein a wall thickness of the sole is reduced at the first portion of the channel relative to a portion of the sole adjacent the channel.

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, and a channel located in the body. The channel is configured to influence the characteristics of the impact of a ball on the face, such as by flexing or compressing in response to the force of the impact, exerting a response or reaction force on the face, changing the motion or behavior of the face, and other manners. The head may also include a pair of channels that have a gap between them.
