Abstract
Abstract A humane hunting arrow which is particularly designed to most effectively obtain the utmost bleed-out possible for a given hit in the shortest period of time. The shaft of the arrow is hollow and is designed to facilitate passage of blood therethrough. Further, the shaft may be provided, either on its inside or outside surfaces, with one or a plurality of weakened areas in the form of grooves, scratches, scored or marked lines, or the like, for facilitating shearing of the arrow shaft thereat after the hit has been registered. Clean breakage of the arrow shaft at the point adjacent the animal's flesh facilitates bleed-out. The broadhead arrow tip includes an opening for creating a reservoir near the open front end of the arrow shaft for further facilitating and expediting the passage of blood therethrough. The element for attaching the broadhead to the shaft allows the complete inside diameter of the arrow shaft to be free of obstructions to further facilitate bleed-out. The attachment element further provides a tension arrangement which allows the pointed broadhead to easily enter the hide and to slide off bone and hard cartilage beneath the hide to enable the broadhead to penetrate the flesh of the animal deep enough to even further facilitate bleed-out.
