Abstract: A golf club head includes a golf club head body and a complex hosel. The golf club head body includes a neck portion located at a heel-side portion, and a connecting portion formed on the neck portion. The complex hosel is constructed from a one-piece tubular member made from a two-layer or multi-layer complex substrate combined along a longitudinal direction such that the complex hosel has at least one first tubular, segmental wall and at least one second tubular, segmental wall that possess two different characteristics of vibrational absorbability and elastic deformability. The complex hosel can provide different vibrational absorbability and elastic deformability characteristics in different radial directions of the neck portion of the golf club head body when assembled.

Abstract: A golf club head includes a golf club head body and a striking plate connected thereto. The striking plate includes a first plate, a second plate and elastically deformable spaces. The first plate has a front surface to provide a striking surface, and a rear surface to provide a first connecting surface. The second plate has a front surface to provide a second connecting surface, and a rear surface. The first connecting surface of the first plate is attached to the second connecting surface of the second plate to form the striking plate which is connected to a front portion of the golf club head body. The elastically deformable spaces are formed between the first connecting surface of the first plate and the second connecting surface of the second plate.
