发明名称 Putter golf club with alignment features
摘要 A putter golf club with alignment features includes a handle shaft, a hosel connected to the handle shaft, and a head connected to the hosel. The head includes a front blade which includes a blade back surface which extends vertically in a first vertical plane. A pair of obliquely intersecting upper surfaces, intersecting at a body peak, are located behind the blade back surface and have a vertical height lower than the blade back surface. A body step face is located behind a portion of the upper surface at a predetermined distance away from the blade back surface. The body step face extends vertically in a second vertical plane. The first vertical plane and the second vertical plane is parallel to each other. The predetermined distance between the blade back surface and the body step face define an alignment region. Preferably, the hosel includes planar sides that are aligned with the first and second vertical planes.
