Abstract: A putter has an elongated head with a face along a long side of the head and an end surface along a short side of the head. The shaft can be positioned to strike a ball with either the face or the end surface. The end surface may have a loft of 5 degrees or more. The shaft is held in each position such that it does not move appreciably while putting, but can be moved to another position by a golfer, optionally with or without tools. In some embodiments, all contact between the shaft and the head is made through one or more resilient, non-metallic materials such as rubber. In some embodiments, a ball on the end of the shaft is held in a cavity in the head by an annular nut. O-rings or other elements separate the ball from components fixed to the head and the nut can be tightened or loosened to adjust the friction provided by the O-rings or other elements. In some embodiments, the shaft can alternately be made fixable or moveable relative to the head by manipulating, for example twisting, the shaft.

Abstract: A golf puffer has a cylindrical tube mounted horizontally behind the putter face with its front end aligned behind the sweet spot. The rear end of the tube is open.
