Anviliron, a stout staff IS a formidable weapon. I have never been taught any martial art specifically with a staff, but the moves I learned from the Army in bayonet fighting back in the 1960's would surely apply. I don't know if they are still as thorough in todays Army, what with a short plastic/aluminum rifle and all.
Bayonet fighting is not just about sticking someone with the pointy end of the rifle. There are parrys, thrusts, slash-n-smash, butt strokes, a bunch of stuff.
