A simple, but quite crap and occasionally pointless trick that reverses the direction of the staff. Comes in plenty of variations, two of which are illustrated. [If you can't tell, you cradle the stick, then while it continues up with it's momentum, you take your forearm underneath it, to the other side where you pull it down in the opposite direction.] This crap trick can't be done fast cos it replies on gravity to slow the momentum of the staff, too much speed and gravity won't be able to do the job.
