Pole Flail
From AmtWiki
A weapon previously used in Amtgard that is now illegal, a pole-flail was a flail mounted on a long polearm, often 10' or more. This was considered to be an extremely cheesy weapon, it was not unheard of for a mediocre fighter to run off 20 or more wins in a row in remote lands when they would build one of these weapons.
