The present invention is directed to a golf club head with an improved striking surface. Grooves are machined into the strike surface with tight tolerances. The grooves have sharp edges, radiused ends, and a draft angle between about 2° and 12°. The striking face is machined such that it has a uniform texture with a roughness of more than 40 Ra. The grooves may contain a plurality of portions, including a radiused or angled portion, a portion having substantially parallel walls, a portion having a v-shape, and a curved portion. The grooves may also be characterized by various dimensions, including draft angle, inclusive side wall angle, width, depth, cross-sectional area, spacing, and pitch ratio. Preferred values for these dimensions are provided. A golf club head having a variety of groove types and a set of golf clubs with grooves varying among the individual clubs of the set are also disclosed.

Golf putter with lead glass head
InactiveUS20060063607A1Improve put abilityImprove abilitiesBall sportsGolf clubsOperating temperature rangeWorking range
An improved golf putter is disclosed that is constructed having a head made from a lead glass material containing at least 24% lead oxide in its formulation. The lead glass material formulation is heated to a full melting point of about 2500° F. and maintained at such temperature to remove impurities and bubbles before being reduced to a working temperature range of 1500°-2000° F. While in the working range, the lead glass material is press molded into the desired shape of the putter head or otherwise formed into billets that are milled or machined using conventional glass cutting techniques. Upon formation of the desired shape, the body of the putter head is annealed to remove stress in the lead glass material and thereafter the exterior of the putter head is treated to mechanically strengthen the surface area and prevent chipping of the putter head. The resulting lead glass putter head exhibits a density between about 3.0 to 5.0 grams / cm3 and a Young's modulus between about 50 to 70 GPa that cause the putter head to impart high energy transfer to the ball upon impact with minimal vibration of the head for greater feel of the impact and consistency in putting. The lead glass putter head may be formed into a variety of configurations each adapted to affix to a conventional putter shaft.
