The Boar Sword

S6, E24: Four bladesmiths must scavenge a construction site to salvage their own knife-making materials. The smiths are then presented with an additional physical challenge when they are required to use a hand-cranked coal forge for the first round. After a critical error sends one competitor home, the three remaining bladesmiths must move on to the even more challenging round 2. Eliminating one more smith, the remaining two head to their home forges where they'll attempt to re-create a historic hunting weapon: The Boar Sword. Which smith will return to the forge with a weapon mighty enough to be crowned Forged in Fire Champion and earn a check for $10,000?
