A putter head is provided with a plane, flat golf ball engaging surface which extends between opposite ends of the putter head. Mounted in a recess formed in the putter head rearwardly of its face is an adjustable sighting line support having in its upper surface an elongage sighting line which registers at one end with the face of the head, and extends rearwardly therefrom. The support is mounted for limited adjustment about an axis that extends parallel to and is spaced rearwardly of the face of the putter head. In one adjusted position the sighting line extends at right angles rearwardly from the putter face in a manner similar to conventional putter sighting lines. However the support is mounted for limited rotational movement for up to at least 10° either clockwise or counterclockwise about its pivotal axis thereby to cause the sighting line to be secured in any one of a plurality of different angular positions other than 90° relative to the face of the putter head. The support is secured releasably in each of its adjusted positions by a screw which extends through the bottom of the putter head and threads into an internally threaded recess in the sighting line support.
