Patent Images
1. A metal wood golf club head adapted for attachment to a shaft comprising:
- a substantially hollow club head including a heel portion, a toe portion, a crown portion, a sole plate, and a front face;
a center point on the sole plate defining the lowest point of the club head, the center point being directly below the club head center of gravity when the club head is at a lie of about 59 degrees;
a heel secondary weight and a toe secondary weight, each secondary weight having a center of gravity positioned a predetermined distance from the center point; and
the center of gravities of the heel and toe secondary weights each being at least 0.5 inch rearward of the center point, at least 0.75 inch from the center point towards the heel for the heel secondary weight and towards the toe for the toe secondary weight, and a maximum of 0.25 inch above the center point,wherein the secondary weights interface with the club head at a generally concave region such that each of the secondary weights bulges outwards of the natural contour of the club head.
