Sword of Perseus

S7 E1: Four bladesmiths are sent on an Odyssey worthy of the Greek Gods: forge a blade from Greek armor and artifacts using the Go-Mai, or the five-layer technique. The smiths wrestle with steels of varying hardness to try to create a blade that would make the weapons God Hephaestus proud. Two smiths get through the brutal testing and head home to re-create the mythical Sword of Perseus. Which smith will return to the forge with a weapon formidable enough to take down the mighty Medusa, and be crowned "Forged In Fire" Champion, earning a check for $10,000?
