1. A golf club head, comprising:
- a golf club head body including a ball striking face, a top, a bottom, a heel edge, and a toe edge, wherein the ball striking face is constructed at least in part from a first material having a first hardness, and wherein the ball striking face further includes;
(a) a first elongated channel extending from a top-to-bottom center line of the ball striking face toward the heel edge and from the top-to-bottom center line toward the toe edge (b) a second elongated channel separated from the first elongated channel at the ball striking face by a first portion of the first material, wherein the second elongated channel extends from the top-to-bottom center line of the ball striking face toward the heel edge and from the top-to-bottom center line toward the toe edge and (c) a first groove defining a first recess in the first portion of the first material between the first elongated channel and the second elongated channel, and wherein, at the top-to-bottom center line, a first edge of the first groove constitutes the first material and a second edge of the first groove opposite the first edge of the first groove constitutes a first fill material, wherein the first groove is adjacent the second channel and the second channel extends deeper into the club head, measured in a direction perpendicular to the ball striking face, than the first groove;
a first fill material partially filling the first elongated channel, wherein the first fill material has a different hardness than the first material of the ball striking face, wherein a first portion of the first fill material extends flush to the ball striking face and a second portion of the first fill material defines a second groove, and wherein a first edge of the second groove constitutes the first fill material and a second edge of the second groove opposite the first edge of the second groove constitutes the first fill material; and
the second fill material partially filling the second elongated channel, wherein the second fill material has a different hardness than the first material of the ball striking face, wherein a first portion of the second fill material extends flush to the ball striking face and a second portion of the second fill material defines a third groove, and wherein a first edge of the third groove constitutes the second fill material and a second edge of the third groove opposite the first edge of the third groove constitutes the second fill material, and wherein the first fill material is separate and independent from the second fill material.

Abstract
The invention is a golf club head with a strike face including a first elongated channel and a second elongated channel which both extend from a top-to-bottom center line of the striking face toward the heel edge and the toe edge of the strike face. The channels can be filled with a fill material, for example a polymer, and a groove may be defined in the strike face or in the fill material of one or more of the channels. The height of the channels, the hardness of the fill material, and the positioning of the groove can all affect the performance of the golf club head. In some embodiments, the golf club head is a putter-type club head.

9. A golf club head, comprising:
-
a golf club head body including a ball striking face, a top, and a bottom, wherein an exposed ball striking surface at a top-to-bottom center line of the ball striking face includes; (a) a top-most groove edge, (b) a bottom-most groove edge, and (c) a plurality of grooves defined in the ball striking face between the top-most groove edge and the bottom-most groove edge, wherein a first subset of the plurality of grooves includes a plurality of grooves having a first edge formed from a first material of the ball striking face and a second edge opposite the first edge formed from a second material of the ball striking face, and wherein the first material is different from the second material, wherein a second subset of the plurality of grooves includes a plurality of grooves having a first edge formed from the second material and a second edge opposite the first edge formed from the second material, and wherein, at least 25% of the top-to-bottom center line of the ball striking face from the top-most groove edge to the bottom-most groove edge includes the first material, at least 20% of the top-to-bottom center line of the ball striking face from the top-most groove edge to the bottom-most groove edge includes the second material, and at least 35% of the top-to-bottom center line of the ball striking face from the top-most groove edge to the bottom-most groove edge includes open space. - View Dependent Claims (10, 11, 12, 13)
