Michael Radiff, known on stage as “The Iron Jaw,” is a Las Vegas–based aerialist, dancer, and acrobat specializing in the daring Iron Jaw act—suspended solely by a mouth-held bite plate, he flies through the air performing spins, swings, and lifts . Earlier this year, during Q Productions Las Vegas’ The Daredevil Circus of Thrills show in Taiwan, Radiff achieved a Guinness World Record by lifting an astonishing 185.8 kg (409.6 lb)—a feat documented via his Instagram reel. A prominent performer in Q Productions Las Vegas’ roster, he has starred in crowd‑favorite shows like Holiday Dreams and Viva Le Cirque!, where his signature Iron Jaw routine is a consistent standout. From gravity-defying spins to jaw-dropping strength, Radiff combines vintage circus bravado with modern theatrical flair. Whether soaring above the stage or pushing the boundaries of human capability, he remains one of Q Productions Las Vegas’ most electrifying talents.
