Urumi

Commonly known as a whip sword, this deadly weapon is fashioned from one to four 5-foot-long, razor-sharp blades of flexible steel, almost like a metal cat-o'-nine-tails. The weapon is wielded by whipping the blades at one's opponent. The coiled blade is fine and flexible enough to be worn as a belt, and its wielders often carry the blades wrapped around themselves in this fashion.
