摘要： Described herein are iron golf club heads and sets of iron golf clubs that have variable weight distribution. Each iron golf club head has a cavity and a groove with a raised portion disposed therein. The groove and the raised portion can deepen the center of mass depth and lengthen the effective face length of the iron golf club. The width of the groove may vary between each golf club in a set of iron golf clubs, such that the width of the groove of the long irons is greater that the width of the groove of the middle irons, and the width of the groove of the middle irons is greater than the width of the optional groove of the short irons. Other aspects, embodiments, and features are also claimed and discussed.

摘要： A golf club having a value of L not less than 45.5 inches, with L representing a club length measured with a 60-degree method, includes a shaft, a grip attached to one end of the shaft, and a head attached to the other end of the shaft. A value of r/L is equal to or not smaller than 0.658 and equal to or not greater than 0.732, where r represents a distance from an upper end of the grip to the center of gravity of the golf club. Thus, a long-length golf club achieving an increased head speed can be obtained.
摘要翻译： 具有L值不小于45.5英寸的L的高尔夫球杆，L代表以60度方法测量的球杆长度，包括轴，附接到轴的一端的手柄和附接到另一端的头部 的轴。 r / L的值等于或不小于0.658并且等于或不大于0.732，其中r表示从把手的上端到高尔夫球杆的重心的距离。 因此，可以获得实现提高头速度的长距离高尔夫球杆。
