A recess is in the rear surface, the recess having a first portion in the blade-like upper mass and a second portion in the muscle-like lower mass. An insert may be provided in the recess, and such insert may substantially fill the recess and may include a back surface having a second contour which is different from the first contour of the club head rear surface. | 09-24-2009 |
| 20100087272 | Golf club head having a displaced crown portion - A hollow wood-type golf club head having an increased weight budget and improved mass characteristics at minimum structural mass is disclosed. The club head has a striking face portion, a sole portion, a skirt portion, and a crown portion having a total surface area. A hosel portion joins the club head for connecting a shaft to the club head. The crown portion has a major crown portion and a minor crown portion, the major portion having greater surface area than the minor portion, and the major portion being displaced vertically lower relative to the minor crown portion. The major crown portion may have a generally concave curvature and the minor crown portion may have a generally convex curvature such that the major crown portion is in effect inverted with respect to the minor crown portion. The major crown portion may be upwardly inclined from the heel to the toe of the head. The head may exhibit a parabolic top view silhouette. | 04-08-2010 |
