Abstract
Abstract A golf club having a shaft, a handle which affixes to one end of the shaft, and a club head which affixes to the other end of the shaft at an inverted right angle tee to the shaft. The club head is of the shape of a small trapezoid top portion symetrically positioned on top of a large trapezoid bottom portion. The shaft attaches to the top center of the small trapezoid top portion so that the weight of the club head is equally distributed over entire length of and circumferentially around the shaft. A plumb bob is contained within a cylinder assembly of the handle and is affixed to a removable top portion of the handle. A ball weighted string or string attached to a spring retracts the string into the cylinder when the removable top is replaced onto the handle.
