Abstract
In order to provide enhanced performance from fletching, an integral or slidable stabilizer is operatively associated with an arrow shaft. The stabilizer in either form includes a plurality of radial vanes each of which imparts aerodynamic force to the shaft so as to cause the arrow to roll or 'spin' when the arrow is in flight. In the preferred embodiments of the invention, the radial vanes of the stabilizer have a cross section in the form of an airfoil to thereby induce the roll or 'spin.'
