    摘要: A paddle assembly includes a tubular shaft that is configured to be coupled to a blade of the paddle assembly. The shaft has a shaft length, a first flexural rigidity at a first location along the shaft length and a second flexural rigidity at a second location along the shaft length. The ratio of the first flexural rigidity to the second flexural rigidity can be at least approximately 1.20. The shaft is substantially linear along the shaft length. The shaft has a shaft midpoint. The first location and the second location are substantially equidistant from and on opposite sides of the shaft midpoint. The shaft can have a tubular configuration. The shaft has a plurality of layers of material at each of the first location and the second location. The orientation of the layers of material at the first location is different than the orientation of materials at the second location. A modulus of elasticity of the materials used to form the shaft varies along the shaft length. The shaft can be formed at least partially from carbon fiber materials.

    摘要: An iron-type golf club head (20) includes a body (22) having a front wall (28) with a ball-striking surface (40). The body (22) further includes a rear surface (54) that has external rear cavity (56) formed therein. The rear surface (54) includes an upper portion (58) and a lower portion (60). The upper portion (60) is separated from the lower portion (59) by the external rear cavity (56) and at least one groove (64, 66). The lower portion (60) of the rear surface (54) has a notch (62) formed therein, which communicates with the external rear cavity (56). The golf club head (20) preferably has high moments of inertia Izz and Ixx.
