Adaptive Reach (Quality)

A weapon which offers different grips, allowing it to be made into a reach weapon as a swift action, and returned to non-reach as another swift action. While using it as a reach weapon, it does not threaten adjacent squares and may not be used to make attacks against targets in adjacent squares, until returned to its non-reach grip. While wielded as a non-reach weapon, it may only attack adjacent squares, even if the weapon is large-sized or has more than 10 feet of reach in its reach-weapon grip.
