ABSTRACT:
A tool has an adjustable lie angle, face angle, weight, and shaft length and is used by a golfer to adjust a putter to the optimal lie angle, face angle, weight and shaft length for that golfer. The tool head has a face plate and a sole disposed normal to one another. An angle member has a vertical wall disposed parallel to the face plate and a horizontal wall that overlies the sole. A hosel is pivotally mounted to the vertical wall and a first protractor is fixedly secured to the vertical wall. A marker on the hosel indicates the lie angle on the first protractor. A second protractor secured to the sole indicates a face angle when the shaft of the club is rotated about its axis. Weights are selectively added to the toe, heel, or mid-point of the putter head to determine an optimal weight and weight distribution.
