In the fourth round of the Forged in Fire Invitational Tournament, four modern metal workers must harvest materials from a metal sculpture to forge a needle point Damascus blade. Will they find allies in these alloys, or will someone experience a metal meltdown? When time's up, an especially harsh round of testing leaves only two metal workers standing. These smiths return to their own home forges to recreate an extravagant sword from the elite classes of Renaissance Europe: the duel-ready Flamberge Rapier. Which smith will earn the spot at the metal worker's anvil, and the chance to win $50,000 and be crowned Tournament Champion?
