BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] This invention relates to golf clubs and golf club heads, and more particularly to a golf club head for a putter that has intermittent grooves or recesses which are filled with polymer or similar material. [0004] 2. Description of the Related Art [0005] Those who have played the game of golf are well aware that putting often accounts for nearly half the golfer's total score. Although there are a wide variety of putters available to the golfers, they still seek improved designs that will assist them in lowering their total score. [0006] Golf putter heads have been designed to impart a rolling motion to the golf ball for short distances. The putter is specifically constructed for use in striking the golf ball accurately toward the cup once it has reached the putting green. Typically, the general construction of a golf club includes a grip portion adapted to be grasped by the golfer, a shaft extending linearly downward from the grip portion, to a club head at the end of the shaft opposite the grip portion. Typically, the club head extends traversely to the shaft and the shaft has a neck portion located at one end thereof, which is connected by a hosel to the shaft. [0007] The golfer addresses the golf ball by placing the club adjacent to the ball. The golfer then swings the club in a short, sweeping arc for a desired, but seldom achieved, perfect swing. [0008] Of importance to the control and swing of the golf putter is its balance. The balance is determined by the weight and weight distribution of the golf club in general. For the putter in the instant case, much of this balance is derived from the putter head as it generally concentrates most of the mass of the club in this area. [0009] Also of importance is the striking surface, or the face, of the putter. This is the surface that actually controls and exerts contact with the golf ball. This surface should be one that is predictable, reliable, and for which expected results occur with confidence on the part of the golfer. Most putter faces are flat, exposed metal that only allow but little traction on the ball. While these putter faces are common, their slick and flat surfaces generally do not provide any action on the ball except to strike it and cause it to roll. Other putter faces may have non-flat surfaces that can result in very unpredictable shots. Such unpredictability is generally not resolved by the use of elastic or shock absorbing features. Consequently, a problem remains in the art to provide a golf putter club face that exerts greater traction upon the golf ball during the golf ball strike that generally does not result in unpredictable or errant shots. [0010] Prior attempts have been made in the art with respect to engraved or cast golf club heads and/or inserts having filled recesses and otherwise. Brief descriptions of some of such prior attempts are set forth below. While the descriptions are believed to be accurate, no admission is made by them regarding their subject matter which is solely defined by the patent or reference involved. [0011] U.S. Patent Application Publication No. 2005/0209020 to Burrows is directed to a golf club putter head, including a faceplate groove pattern configured to provide the putter head with an elevated center of gravity. In one preferred form, a club head body defines a faceplate having at least one and preferably multiple elongated grooves formed therein to extend generally in a heel-to-toe direction, with at least one groove positioned above a vertical mid-point of the club head body. The groove depths progressively increase in a top-to-bottom direction so that the putter head center of gravity is elevated to a position spaced above the vertical mid-point of the club head body. When striking a golf ball, the elevated center of gravity functions to minimize initial ball skidding and to promote early smooth ball roll toward a target such as a cup on a golf green. [0012] U.S. Patent Application Publication No. 2005/0090332 to Burrows is directed to an iron type golf club head, including a plurality of weights mounted at a rear side thereof in a spatially laminated array. The club head includes a front impact face oriented at a selected loft angle for striking a golf ball, and a rear side having an integrally formed weight frame protruding rearwardly therefrom. The weight frame defines a plurality of peripheral or perimeter grooves disposed in generally fore-aft spaced relation and adapted to receive and support weights of selected mass. In a preferred form, each weight includes one or more weight elements seated within the associated groove to wrap substantially about the entire periphery of the weight frame, with an outboard marginal edge of each weight element being visible from the exterior of the club head. Abutting ends of the weight element or elements within each groove may be interconnected end-to-end as by welding. [0013] U.S. Pat. No. 6,746,344 to Long is directed to a golf putter head with vertical and horizontal cavities. [0014] U.S. Pat. No. 6,648,774 to Lee is directed to a hollow golf club head comprising a metal striking insert and a composite body. The metal striking insert is molded within the front face wall of the club head body and is securely attached at the outside perimeter of the insert to the composite body and at the front corners of the composite body through the use of a sandwiched structure. The sandwich structure formed at the boundaries of the striking metal insert efficiently dissipates the impact energy affected when a golf ball is hit. The structure also dampens efficiently the vibrations of the shock affected when the ball is hit on the metal striking insert. The present invention of positioning the insert inside the face wall, not extending outside the face wall, uses less metal material which is heavier than the composite material and makes a larger club head at the same total weight of the club head. A larger golf club head that gives a higher moment of inertia is highly sought-after for a hollow club head construction. [0015] U.S. Pat. No. 5,972,144 to Hsu is directed to a method for manufacturing golf club putter heads including four steps: 1. forming a recess in a striking face of a club putter head, 2. adhering a decorative plate with a name or pattern in the recess, 3. pouring epoxy resin solution in said recess and letting it dry up to form an insert block, 4. grinding the upper surface of the decorating plate and the insert block flush with the striking face of the putter head. Then the name or pattern may not wear or disappear even if hit by golf balls for a long period of time. [0016] U.S. Pat. No. 6,083,117 to Hsu is directed to a golf club head that has a recess in a striking face and annular groove formed around the recess. A metal layer is fitted in the recess and an annular resin layer is formed in the annular groove to surround the metal layer. Then preparatory work for plating the whole head can be done quickly, and club heads after treated with plating may be of excellent quality, resulting in lower cost. [0017] U.S. Pat. No. 6,932,716 to Ehlers et al. is directed to a golf club head having a matrix layer composed of an interconnected reinforcement structure and a polymer material. The matrix layer provides the golf club head with a greater coefficient of restitution during impact with a golf ball. The matrix layer is preferably disposed within a recess in the front wall of the body of the golf club head. The interconnected reinforcement structure is preferably composed of interconnected hexagonal cells. [0018] U.S. Pat. No. 6,729,972 to Boord is directed to a golf club preferably in the form of a golf putter that includes a hard stainless steel club head having a striking surface for contacting a golf ball with a recess formed therein. A softer brass plate and an advertising insert closely fit within the recess, and are covered by transparent epoxy which hardens to form a portion of the striking surface through which advertising printed on the insert is visible. The club head further includes a rear recess behind the front recess, between which is defined a thin perforated wall. The stainless steel body, the brass plate, the transparent epoxy, and the perforated wall provide a golf putter which has a large sweet spot and which provides for advertising. [0019] U.S. Pat. No. 5,425,535 to Gee is directed to a perimeter weighted golf club head having a flush mounted polymer insert in the club face which is approximately centered coaxially with the center of mass of the golf club head and a cavity filler. A recess for the polymer insert is either formed in the main body structure of the golf club head during the casting process, or subsequently by machining. A retainer is provided to help secure the insert and cavity filler in both the club face recess and the hollow cavity. The retainer can take the form of a through hole connecting the recess to the hollow cavity and/or lip surrounding either or both the recessed insert opening and the cavity opening. [0020] U.S. Patent Application Publication No. 2005/0020378 to Krumme et al. is directed to a striking face backing for golf clubs, such as a driver, iron or putter, formed of non-uniform geometry or material arranged to create a desired "feel" to the golfer and/or produce a desired effect on the golf ball. For instance, the backing can be arranged to create a variation in mechanical properties across the striking face. The backing designs can be applied behind integral striking faces, or as part of monolithic, unitary striking face, or pixel striking face inserts. The geometry, compression, and rebound properties of the backing are communicated to the striking face. Thus a sweet spot on the striking face of the club may be enlarged and/or shifted and the effects of imperfectly executed impacts may be mitigated. [0021] U.S. Pat. No. 6,951,518 to Solheim et al. is directed to a golf club head, including a face insert disposed in a cavity formed in the front face of the club head. The face insert has a front surface for impacting a golf ball and a back surface having a cavity formed therein for receiving a second insert. A second insert, composed of a material different from the first insert, is disposed in the cavity formed in the back of the first insert. Because the edges of the second insert are not exposed, the second insert can be made of very soft materials including silicone rubbers and gels, which would not be suitable for use in an application in which the edges are exposed. [0022] U.S. Pat. No. 4,679,792 to Straza is directed to a golf putter head having a body with a cavity in its front face containing an insert member having a front, ball striking face co-planar with the front face of the body. The insert member comprises a honeycomb cellular structure with the cells of the structure filled with a resilient, epoxy material. The walls of the cellular structure are mounted in the cavity perpendicular to the inclined club striking face surface and have exposed cell edges co-planar with the surface of the resilient material and the club striking face surface for simultaneously impacting a golf ball. The putter head is further formed to have an upwardly curving sole. A curved neck attaches the head to the club shaft to position the striking face in line with the axis of the club shaft.
