A putter-type golf club head and method of manufacturing said golf club are herein disclosed. The putter has a body, a face surface, a rear surface, a sole surface, a crown surface, and a heel surface. To reduce the reflective glare off the crown surface and to improve the ease of alignment, the putter includes various curved boundaries between surfaces of the club head. Multiple sections of the crown connect with the heel surface through curved transition regions, which reflect the light differently than the crown surface and thus serve as alignment aids.
