Fredson Paixao - Master of the Locking of the Wrist

Known as the wristlock master, Fredson Paixao was recently interviewed by the cats at BJJ Hacks on his small joint manipulation skills.  This is a great video showcasing a rarely respected submission which is essential in self defense!  Think about it... you ain't grabbing a weapon, my arm, my clothing, or anything for that matter,
with a broken wrist.
