Abstract
Embodiments of golf club heads having a hydrophobic surface and methods to manufacture such golf club heads are generally described herein. The golf club heads are configured to comprise a ball-striking face and at least two channels formed therein. The channels are separated by a land portion of the ball-striking face extending therebetween. The land portion is associated with at least a first step portion extending at a first elevation and a second step portion extending at a second elevation, the second elevation being higher than the first elevation relative to a bottom of the channels. Each of the first and second step portions is so dimensioned as to be associated with a substantially hydrophobic contact angle.
