The Chinese War Sword

Four smiths get ready for a cage match when they are tasked with not only freeing their tools from a steel grate, but also forging a knife from it. After opting for canister, the competitors fight the clock and heat in an attempt to turn in a great blade to the judges. After a relentless round of testing, the two remaining smiths head home to recreate a Chinese War Sword. Which smith will forge a blade worthy for battle, earning the Forged in Fire title, and $10,000?
