Johns (Cole Hauser) Baton

This is the metal extending club used by Cole Hauser in his role as the Merc William J. Johns in Pitch Black.
Johns is seen to be using this baton at various points throughout the film, most memorably when Riddick drops from the ceiling and Johns has to beat him to the floor with it – saying his line: ‘One of us is going to get hurt one of these days..and it aint gonna be me!’
