  • Kayak paddle with rotating handles
    Patent number: 5851132
    Abstract: An improved kayak paddle for recreational or competitive paddling, which has handles affixed perpendicular to the shaft or shafts, which handles rotate on axles as the paddle is used, to reduce twisting of the wrists and other joints of the paddler and improve efficiency and comfort. The shape of the paddle blades is such that water falls off the corner of the blades and does not run down the shaft to wet the hands of the paddler.
