A golf putter that allows the golfer to effectively aim the putter blade from behind the ball while looking down the intended direction of roll of the ball and to maintain this established direction while the golfer is moving into the normal putting position.

The juncture between the sole and at least one side of the golf putter head forms a sharp corner which extends generally parallel to the longitudinal axis of the head and serves as an edge for biting into the green surface and resisting endwise turning of the club head relative to the desired putting line as the golfer starts tilting the club head from an aiming position toward an address position. The sole has at least two convex contact points for maintaining rolling contact with the green and resisting turning of the club head as the biting edge is elevated from the green. The opposite ends of the head are provided with striking faces and the sole has upwardly curved outer end portions for riding over the ground when the ends are used to strike a golf ball. The slope of the green can be determined with a ball trough in the club head and indicia on the club head can be used to check alignment of the putter face when the head is in both the aiming and address positions.

The characteristic feature of the herein disclosed method resides in that it involves a zone control over temperature and humidity of articles being treated within the space of a tunnel chamber, the articles being blown with an air agent having a temperature of 40.degree.-100.degree. C. prior to the step of temperature increase whereas in the zone of said temperature increase the articles are treated with a steam-air mixture for a period of 1-6 hours, the temperatures and humidity of the mixture being gradually increased to their permissible values corresponding to the given type of articles being treated; in so doing the articles in the isothermal curing zone are affected for a period of 2-6 hours with a heat-carrying agent having a temperature of 60.degree.-95.degree. C. and a relative humidity close to 100% while in the cooling zone the articles are blown with a cooling agent having a relative humidity of 35-90% for a period of 0.3-1.5 hours. The characteristic feature of the apparatus for realizing the method of this invention consists in that the apparatus includes a chamber for pre-drying of articles, said chamber being provided with air ducts and communicated by means of one of the latter air ducts with an air screen manifold located at the inlet to the tunnel chamber.

A precision made putter including a shaft and head in which the shaft has a compound reverse curve above the point of attachment to the head and is so positioned that the putter head and shaft are balanced with the club face upward and parallel to the ground, dictating the proper position of the shaft curves in relation to the head, and where the putter head has alternate stripes all at right angles to the face of the head and where the foot is slightly rounded toward each side and toward the rear from the face.

A golf club having weight members located at the toe and the hosel of a cavity back club head. The toe weight and hosel weight each have a center of mass which is located above a horizontal line drawn through the center of gravity of the club head when the club head is lying at address. In one preferred embodiment the toe weight extends rearwardly from the toe rim of the club head and rearward of a plane containing the rear edges of the club head to increase the back weighting and therefore the dynamic loft of the club head. The hosel weight extends outwardly from the hosel and is located anywhere within a 90.degree. segment of the outer periphery of the hosel. At one extreme position, the hosel weight extends outwardly in a plane which is generally parallel to the leading edge of the club head and at another extreme position the hosel weight extends rearwardly and generally at right angles to the leading edge of the club head.
