You’ve seen them in luau shows, those bare-chested dancers in lavalava spinning flaming fireknives to the beat of Polynesian drums. But tonight, the traditional Samoan dance will be performed to a very different beat — old-school hip-hop — during the Vaimatina King of the Streets Fireknife Battle at the Polynesian Cultural Center’s Hukilau Marketplace.

“It’s exciting because there is nothing else like it. When you see how you can do the Dougie with the fireknife, it’s crazy,” said event emcee Jason Ava, 36, referring to the hip-hop dance style.

“You can count on PCC to deliver that traditional fireknife dance, but what you are going to see at the street battle is something you can’t say you’ve seen before.”

The New Year’s Eve fireknife “street battle” debuted in 2013 after three-time world fireknife champion David Galeai and his cousin saw one of their nephews doing freestyle rap battles in which participants exchange colorful and often boastful rhymes. He said they thought “it would be cool to have fireknife like that.”

“Get out on the street and just battle. No rules. You just come and you can dance hip-hop,” said Galeai, 36, who cooks and performs at the Polynesian Cultural Center.

Ava, also known as MC PeekABoo, said combining the two dance styles was a way to keep younger generations of fireknife dancers involved in the activity. “They got bored, they wanted to do something else,” he said. “We decided, hey, why don’t we fuse the two so that way they can expand a little bit? And we watched how much fun they had and so we thought, ‘You know what? I think we might be onto something.’”

The participants dress in hoodies and other streetwear; some perform as clowns, ninjas, magicians or other personas. Skateboards and bicycles are sometimes incorporated into the routines, and one of the dancers has been known to light his shoes on fire and breakdance. The stunts are designed to wow the judges, who this year will award a $1,000 first prize in the senior division for ages 14 and older.

“That will help in the one minute you have. That’s what separates this from a regular fireknife competition,” said Alex Galeai, 38, a past world champion who helped organize the street battle and is another of David Galeai’s cousins.

The judges are past world champion Umi Sexton, former intermediate world champion MJ Mata’u and Cap Tafiti, the main performer in the cultural center’s nightly show, who will be looking for fireknife speed and flow, height of throws and difficulty of moves. Crichton Uale, a professional DJ and emcee, and Tanoa’i Reed, a stunt double for Dwayne Johnson, will score on entertainment value and crowd-pleasing ability, while choreographer Ui Kaitoku will be judging dance moves and creativity.

Most of the competitors are youths from the Galeai family, though “we want to get people from everywhere else to come participate,” said Ava, who works in BYU-Hawaii’s admissions office. The event is meant to be a positive experience for everyone, he said.

“We tell our kids you never have to feel like you are a loser or that you can’t. The only negative thing is if you don’t try. You are rewarded for trying.”

In that spirit, all participants will go home with a prize. Sponsors include David Galeai’s World Fireknife Productions, Polynesian Cultural Center, McDonald’s, Goat Island T-shirts and Eagle Electric, which provided the cash prizes. First prize in the junior division for ages 13 and younger is $100.

The event is free to spectators and contestants. Food stalls and trucks will be open. A public dance with music provided by DJs will follow at about 11:30 p.m.

Organizers emphasize the King of the Streets Fireknife Battle is a family show. “No swearing and keep the music clean,” said David Galeai.
