Four bladesmiths face double the trouble when they are tasked with forging not one, but two canister damascus knives. After a brutal round of testing, only two smiths move forward to build an extremely challenging Cinquedea sword. Who will rise to the doubly difficult challenge and be crowned Forged in Fire Champion and win $10,000?

In this competition, it's all about Japan's shadow warriors--the ninja. Four smiths are challenged to forge their own version of a ninja blade, and in a Forged in Fire first, the smith with the lightest blade wins an extra 20 minutes in the second round. After an intense round of testing, the two surviving smiths return home to recreate the lethal and stealthy Ninjato Sword. Two smiths will enter the final testing battle, but only one will emerge with a check for $10,000 and the title of Forged in Fire Champion.
