US Patent 9341447 Arrow tip mounting apparatus and method

An interface component for engaging an arrow tip to the leading end of an arrow shaft. The device directs impact forces axially and eliminates the shearing and wall collapse of arrow shafts caused by conventional collared arrow head engagement devices which tend to collapse and cut the leading edge of arrow shafts on hard impacts. Engagement to the arrow shaft leading end is provided by an elongated member axially engaged with the bore of the arrow shaft. The exterior surface of the device can be surfaced to interact with passing air during flight of the arrow and increase spin for better accuracy.
