First Claim
1. A golf club head comprising a crown, a sole, a heel side, a toe side, a face, a rear side opposite the face, an edge portion where the crown connects with the sole, and a channel disposed in one of the crown and the sole,wherein the channel comprises walls having at least two sides and a floor,wherein an area of a cross-section of the channel taken in a direction normal to the edge portion is constant along the channel,wherein the channel extends from the heel side towards the toe side via the rear side and proximate the edge portion along one of the crown and the sole, andwherein a heel-most end of the channel is closer to the face than a toe-most end of the channel.

Abstract
A golf club head comprising a channel and an expandable weight that can be removably fixed at any point within the channel is disclosed herein. The channel preferably is disposed on the sole and extends from a heel side of the golf club head, around a rear side, and ends at a toe side of the golf club head. This channel is not constrained to a planar arc, but instead twists as it extends around the golf club head so that it follows the contours, and preserves the aesthetics, of the golf club head. The expandable weight preferably is trapped within the channel so that it cannot fall out of the channel during use, and includes an anti-rotation feature so that it does not twist within the channel and cause an undesirable rattling noise.
