  • Rotary arrowhead assembly
    Patent number: 8043176
    Abstract: An arrowhead assembly includes a blade tube that may rotate in flight at a rate during flight that is independent from the arrow shaft rotation. The assembly, upon and after impact with the target, continues rotational motion of the blade tube to penetrate a substantial distance into the target. Such characteristics are facilitated by the spiral-shaped, or twisting, nature of the blades as well as the rotational motion that is imparted by a spring arrangement of the assembly after compression and expansion of the spring arrangement upon impact.
