Abstract
A putter includes a putter head and a putter shaft with a first end connected to the head and a second end forming a handle for gripping by a golfer. The shaft is connected to the putter head and disposed with respect to the putter head so as to allow a golfer using the putter to address a golf ball with the putter in substantially the same manner as he or she would when using an iron or wood. The shaft includes a first straight portion, a bend, and a second straight portion extending from the bend to the second end of the shaft. The first portion preferably has a lie angle of about 70.degree.-80.degree. and the second portion has a lie angle of about 50.degree.-70.degree.. A weight is formed as part of the shaft, or disposed within the hollow interior of a metal tube forming the shaft, at the first portion of the shaft and part of the second portion, so that the moment of the putter and first portion of the shaft about the bend is substantially the same as the moment of the second portion of the shaft (with attached grip) about the bend.
