    Abstract: An adjustable lie angle putter having an infinite degree of adjustment between a 56.degree. and 79.9.degree. angle from the zero ground plane. The putter head has an elongated slot therein located on the upper surface of the putter with aligned boreholes in the walls of the slot. The shaft is secured to a hosel member which terminates in a tang having parallel flat sides which mate with the slot. A borehole extends through the tang between the flat sides. A pin is secured in said boreholes so as to pivotally secure said tang in said slot. The upper surface of the tang forms arcuate surfaces on opposite sides of the shaft which terminate in flat planar surfaces. The flat planar surfaces terminate in two substantially flat bearing surfaces which meet at an angle. Two threaded boreholes extend angularly through the sole of the putter into the slot and two adjustable setscrews are secured with the boreholes.
