Abstract
A golf putter can be provided with a concave ball-striking surface that causes the golf ball to move toward a target point on the ball-striker axis when the ball contact is. offset from the ball-striker axis. The contour of the ball-striking surface can be varied to adapt the putter head to different target distances.
