Между молотом и наковальней

Four new bladesmiths have their creativity put to the test when they are tasked with making a serrated blade out of only the tools from the table in front of them. They must harvest enough steel to forge the blade, but without melting down a crucial tool they might need later. Then, the final two bladesmiths attempt to forge a Hunga Munga--a behemoth weapon where all four edges must maintain peak performance when put through the judges' gauntlet. Which bladesmith will prove worthy of a check for $10,000 and the title of Forged in Fire Champion?
