Abstract

A projectile includes a body having one of a number of geometric shapes which have a plurality of blades. The projectile may be divisible into two substantially equal portions. The portions have a number of blades disposed across their respective surfaces. Moreover, a blade may encircle the periphery of the projectile and may be sandwiched between the portions once assembled to one another. In one embodiment, the blades may be removed so that they may be replaced when they become dulled through use. Alternatively, the blades may be removed, sharpened, and returned to their appropriate positions on the projectile body.
