Abstract
A metalwood golf club head including upper and lower surfaces, a front ball striking face and a curved rear surface is characterized by a concave projection in the lower surface extending from the face toward the rear surface. The depth of the concavity in the projection is governed by the loft of the club face, with the depth being greater for higher lofted clubs. The concave projection enables the club head to strike to golf ball resting on the ground, and particularly in a poor lie such as in a bunker or deep rough, without the head becoming buried in the ground.
