Abstract
A golf club putter has a putter head including a plurality offset surfaces, each of the offset surfaces containing a respective portion of an alignment figure that has a periphery enclosing an area. Each respective portion of the alignment figure includes respective sections of the periphery. Disorientation of the putter head may be detected by transposition of each portion of the alignment figure with respect to the other portions. Correct orientation of the putter head is indicated by precise alignment of the portions to present the alignment figure without apparent distortion.
