From Chris McKaskell:

 I was thinking about moving the centre around its axis and around objects.

 The staff is a heavy piece if solid ash I shaped with hand tools to make a hefty bo.

 It’s heavy enough that it needs to be moved around – which is to say I must move around it – it’s simply not possible to muscle the weapon around. It becomes an object which has its own mass and must be used in balanced conjunction with my intended movements like strikes and parries.

 Almost like moving a partner.
