Abstract
A putter-type golf club head includes a striking face with a plurality of grooves having a variable depth profile and a variable pitch. Groove variation is tailored to correspond to the golf club heads' moment-of-inertia, mass, or another attribute. A surface treatment method includes selecting a variable depth profile and a variable pitch for a plurality of grooves and surface milling a striking face of a golf club head to form the plurality of grooves.
