what is this weapon?

it is a staff about the size of a jo with half a nuchaku on the end what is it?

 

So-setsu-kon Nunchaku:

 

Long sweeper (as opposed to short sweeper - nunchaku)

If you really want one you should try www.wushudirect.co.uk

I think they have a version in long weapons (although it's got a different name).
