It's a battle royale for four bladesmiths when they are tasked with forging signature blades with an integral knuckle duster from a steel cage and barbed wire. Getting a solid billet from these steels is a challenge all on its own, but forging a functional handle from the same piece is a whole different story. After two frantic rounds and a brutal weapons test, two finalists return to their home forges for one final challenge. They must recreate one of Scotland's most famous and feared weapons: the Lochaber Axe. Which axe will lock in the title of Forged In Fire Champion and take home the $10,000 prize?
