Abstract:
A metal wood golf club comprising:a metal head having a front substantially vertical striking face wall and an ellipsoid configured body defining an inner cavity defining a cavity length, said face wall secured to said ellipsoid body, said face wall produced from a hard metal selected to minimize or avoid flexing of the metal of said face wall when impacting a golf ball and thereby to minimize velocity loss that occurs in rebounding of a golf ball from the face wall; a substantially vertical second wall inset from said face wall and secured substantially at its entire periphery to said ellipsoid body at a position rearward of said face wall and said second wall, said second wall spaced no greater from said face wall than half the length of said cavity; and said face wall, said second wall and said body wall portion cooperatively structured to define an enclosed and empty sub-cavity whereby transfer of ball impact to the second wall occurs only through the interconnecting body wall portion.
