Throwing arrow
Abstract:
A projectile arrow apparatus not requiring a bow comprising a grip member, a notch opening formed within the shaft and a string tether comprising a knot formed in a first end. The tether is retained taut between the knotted end tightly wound within the notch opening and a second end wrapped around a palm of a user's hand while the user's hand grips the grip member. The apparatus is aimed and thrown forward mimicking a typical throwing action to render the apparatus air-borne as the knotted end of the tether unwinds and releases from the notch. Forward projectile forces pull on the tether as the user's arm moves in a throwing arc, directing the arrow in a desired trajectory toward a preferred target and sending the arrow significantly further and with significantly more force than if thrown by hand.
