    • An enlarged metalwood golf club head, including a hollow body and a weight pad. The hollow body includes an inner cavity surrounded by sole portion, an impact face, a heel portion, a toe portion, a rear face portion joining the heel portion to the toe portion and a crown portion joining the impact face, the toe portion, the heel portion and the rear face portion. The heel portion includes an opening for the introduction and connection of a shaft. The opening defines an axis. A weight pad is located within the cavity of the body along the sole portion so that the center of gravity of the golf club head is located beneath the center of the impact face and closer to the heel portion than the toe portion. Desirably, the metal head has a size and a shape such that the head has a high moment of inertia about the vertical axis y passing through the center of gravity so that the head has increased resistance to horizontal rotation upon off-centered strokes.
    • 一个放大的金属木头高尔夫球杆头,包括一个中空的身体和一个重量垫。 中空体包括由鞋底部分包围的内腔,冲击面,脚跟部分,脚趾部分,将足跟部分接合到脚趾部分的后表面部分和将冲击面,脚趾部分, 后跟部分和后表面部分。 鞋跟部分包括用于引入和连接轴的开口。 开口定义一个轴。 重量垫沿着鞋底部分位于身体的腔内,使得高尔夫球杆头的重心位于冲击面的中心下方并且比脚趾部分更靠近跟部。 理想地,金属头具有尺寸和形状,使得头部围绕穿过重心的垂直轴线y具有高转动惯量,使得头部在偏心行程上具有增加的对水平旋转的阻力。
