  • Light weight split hosel and putter head
    Patent number: 4951949
    Abstract: A split hosel and putter head is provided. The split hosel is of an inverted V-shape and is connected by a short shank at the top to a golf club shaft and at the bottom to the heel and toe of the putter head through slots in the head. The hosel is light in weight and when employed with a putter head of perimeter weighting construction concentrates the impact of the putter stroke upon the golf ball to minimize torque and twisting occasioned by off-center impacts.
