Is my Staff a Stick?

[MacGregor]

I'm trying to make a cool Quarterstaff for a DF game I'm running, so I'm looking through the weapon modifiers. Under Balanced, it says "All weapons except sticks and improvised weapons".

So what weapons count as 'sticks'? Only pieces of wood that haven't been shaped or carved or made into a weapon? Or any weapon made entirely out of wood?

Mostly I'm wondering about Staffs, but other melee weapons come to mind. Clubs, tonfas, lances, batons, wooden stakes, sharpened sticks, etc...

For the moment I am assuming that a Staff is not a Stick. At least until I hear some other opinions.

Thank you
