Abstract
An arrow attachment for inducing hemorrhaging in a big game target has at least one cutting blade movable from a retracted, inoperative position to a projected operative cutting position, the blade being provided with an actuating member which projects outwardly relative to the blade and which, upon being subjected to an impact resistance, functions to move the cutting blade from the retracted position toward the projected position.
