The best way to make a club would be to somehow weld/attach a cylindrical 或者 rectangular shaped piece of a hard material, such as stone 或者 metal, onto a metal 或者 wooden handle. This is the traditional way to make 俱乐部 that warriors used in the prehistoric to middle ages.
Also, why the hell do 你 want a club? There are much better weapons out there with today's technology. 哈哈 OP is a noob.
