Fire Knife Dance

Although commercial fire knife dancing is performed with wooden poles wrapped in burning towels, traditional knife dancing was composed of a machete wrapped on both ends with a towel with a portion of the blade exposed in the middle.  The Samoans call it "siva afi".
A similar demonstration of a Samoan warrior's prowess is called the "ailao" - twirling, throwing, catching, and dancing with a war club.
