Abstract
An improved golf putter featuring a two piece cylindrical clubhead comprising a rod constructed from a hard material and fastened inside a thin walled tube cast from soft, malleable material such as copper. The club and clubhead are designed so as to improve balance, efficiency, and feel, and to impart initial forward rotational spin to the golf ball. The shaft is connected to the clubhead in such a manner as to align the shaft with the center of the clubhead, thereby maximizing the size of the 'sweet spot,' and to create a lie angle of between 65 and 76 degrees.
