Abstract

An arrow apparatus is disclosed comprising an arrow point alignment structure having a tapered leading end disposed on an outer surface of an arrow shaft. The arrow point may also comprise a tapered aperture defined therein for receiving and mating with at least a portion of the tapered leading end of the arrow point alignment structure in order to bring the arrow point into axial alignment with the arrow shaft. The arrow point alignment structure may be integrally formed with, or affixed to, the outer surface of the arrow shaft or affixed to a portion of the arrow point. The arrow apparatus may also further comprise an insert at least partially disposed within the arrow shaft. The insert may comprise a first insert portion removably attached to a second insert portion that weighs less than the first insert portion. Various arrow points and corresponding methods are also disclosed.
