Unknown Weapon

[clockwork]

Hi guys I picked up a new piece while in china and I have no idea what it is. I was told the martial art masters were the only ones that used it. It reminds me of a skinny mace with a protective cover. It is 20 and 3/4 inches long total and 18 and 1/4. with out the cover. it has a hole in the back and a sliding metal clasp to keep the cover from coming open. The second item I picked up in china is a hand cannon and it 37 and half centimetres or 15 inches long at the widest point is 2 and 1/4 inches I think there is some writing near the base but not sure how to clean it with out hurting it. the bore is 3/4 inch. the length of the barrel is about 10 and the wood pole goes in about 3 and 1/4. Fernando will be posting pics soon 4 me.
