发明名称 High Moment of Inertia Putter Having Adjustable Weights
摘要 A golf putter head of triangular shape. A ball-striking leading wall has a first breadth greater than a second breadth of a trailing wall. The leading and trailing walls are interconnected at their respective opposite ends by sidewalls that converge toward one another. A web interconnects the leading and trailing walls along a longitudinal axis of the golf putter head. A first embodiment may include a trailing copper weight and side wall aluminum weights. A second embodiment may include three copper weights, a third embodiment may include three copper-tungsten weights, and a fourth embodiment may include three tungsten weights. The weights are removable so that a putter having a low swingweight or a high swingweight can be brought up to or down to a standard swingweight. The weights may also be mixed in the second, third, and fourth embodiments.
