Forged in Fire: Season 8, Episode 21

8 - 21: Deadly Duo

Four smiths face double the trouble during this Forged in Fire challenge when they have to make a single blade using two different techniques--san mai and layered damascus. After surviving twice the amount of brutal testing, the two smiths left standing return home to recreate a pair of lethal weapons used by the Philippine Marine Corps--the Ginunting Swords. The smiths face off in one last round of testing that's so intense, it'll have them seeing double, but only one can come out on top to win $10,000 and the title of Forged in Fire Champion.
