ABSTRACT:
An controlled penetration arrow tip which has a penetration enhancing section at the point which is followed by an energy imparting or energy transferring section. This energy imparting section may resist complete penetration of an animal or penetration into unintended material, such as trees. The body and/or trailing end may be tapered to improve penetration or aerodynamic characteristics. Facets or scallops may be used on the impacting end, body, and/or trailing end in order to improve aerodynamic characteristics. The trailing end may be truncated, flared, flanged, or otherwise made larger than the arrow shaft to increase the damage of tissue and/or the energy transferring characteristics and/or to render removal from animal difficult. This truncated section may be split, cut, notched, or otherwise separated to improve aerodynamic and/or tissue damaging characteristics. Ribs, turbines, fins, blades, or other outwardly extending surfaces may be used to improve tissue damaging and/or aerodynamic characteristics.
