Между молотом и наковальней

In the first of a four episode event we're calling SUPERSIZED, four smiths must salvage steel from a massive railroad track to make their signature big blades. Then, two smiths head back to their home forge to build the biggest weapon in Forged in Fire history: a monstrous seven-foot sword wielded by legendary warrior, Grutte Pier. Which smith will rise to this colossal challenge and take home $10,000?
