Four bladesmiths must create a blade out of high carbon steel while also forging the hammer they'll use to make it. After an extraordinary round of testing, only two move on to the final round where they'll have just five days to create a weapon known for its deadly prowess against armored soldiers–the Falcata. Will the blade's unique handle shape leave them open to a devastating blow, or will one smith be able to slice their way to the $10,000?

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.
