  • Golf sand wedge and putter
    Patent number: 5090703
    Abstract: A golf club for use as a sand wedge and as a putter, in which the ball-engaging face of the club head has a rectangular central opening through which sand can pass during a stroke while the club is used as a sand wedge. Upper and lower flat ramp surfaces are dimensioned, angled and spaced so as to contact the golf ball at intermediate portions between the outer and inner edges of the ramp surfaces. The upper and lower edges of the ramp surfaces are spaced apart by a distance approximately equal to the diameter of the golf ball to be driven, so as to avoid undesirable binding or cutting of the ball.
