In a new twist on the classic car challenge, four smiths have to create a knife from the most mangled mess of a vehicle ever seen on the forge floor. After their weapons are driven to the brink in an intense round of testing, the two surviving smiths return to their home forges to recreate two of the most unique weapons from history--a matched set of curved katars. In the end, only one smith's set of weapons will prevail, earning him $10,000 and the title of Forged in Fire champion.

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?
