  • Patent number: 5911640
    Abstract: An improved hunting tip in which helical blades extend around the inner core of the head and causes the arrow to rotate during flight. The rotation creates a stabilizing motion, and when the arrow enters its prey, the outer edges of the helical blades, being sharpened, create an "auguring" effect causing increased bleeding in the prey and having a more lethal effect. The lethal effect caused by the hunting tip is further increased by the fact that the helical blades extend forward and around the center sharpened tip of the hunting tip, thereby increasing the initial cutting diameter of the arrow. The helical blades are rotatably attached to the hunting tip, thereby providing for removability of the blades. This simplifies repair and, therefore, increases the useful life of the hunting tip.
