Patent ID: 6860821

Claim:
A golf shaft produced by baking a plurality of fiber prepreg layers, the shaft being a laminate comprising: a main layer consisting of resin-impregnated high-strength high-elasticity fiber; a metal wire layer laid over the main layer, wherein the metal wire layer comprises a first metal wire layer and a second metal wire layer with a transparent layer disposed between the first and second metal wire layers, wherein the first metal wire layer is helically winded around the shaft and the second metal wire layer is helically winded over the first metal wire layer to form the metal wire layer; and a layer of low-elasticity fiber, laid over the metal wire layer, impregnated with resin through which the underlying metal wire layer can be seen; wherein a material layer forming an outermost protective surface overlying the second metal wire layer is in contact with the transparent layer, wherein the transparent layer is disposed across opposing planar faces of the first metal wire layer and the second metal wire layer and contacts the main layer in spaces between the first metal wire layer and contacts the layer of low-elasticity fiber layer in spaces between the second metal wire layer.
