The Quaterstaff is an overlooked weapon that anyone who regularly goes into the countryside could use openly. It is just an oversized walking stick really and does not look like a weapon at all. They are very effective as both an offensive and defensive weapon (remember Little John who kicked Mr Hoods arse lol). In Japan they are known as JO staff, but it's the same thing really.
