Golf club head and method of manufacturing the same

Abstract

A golf club head comprises a body including a top and a bottom and a hosel connected to the body. The body comprises a forward face defining a leading edge and an opposing rearward facing surface defining a trailing edge. At least one weight shifting element is positioned on the rearward facing surface. A sole extends between the leading edge and the trailing edge and defines a center portion, a first end surface and a second end surface. A static bounce angle is equal to an effective bounce angle when the center portion is square with the ground, and the effective bounce angle is greater than the static bounce angle when the center portion is not square with the ground and the second end surface is positioned away from the ground.
