Abstract

Abstract The golf putter includes an elongated tapered body having a vertical plane of symmetry extending in the direction of putting motion and an adjustable putting face secured to the leading surface of the tapered body. The putting face is provided with a loft no greater than 10° and the face is pivotable about a horizontal axis on the plane of symmetry so that the face can be adjusted to a horizontal position for a particular angle of the putter shaft relative to the vertical and then secured to the body. The weight of the putter head is also adjustable.
