7x13 - Forged in Fire

Four smiths get ready for the ultimate showdown when they are tasked with forging a camp knife out of steel harvested from a barbecue. Temperatures run high as they must first figure out what steel is high carbon and what is mild. After their blades are grilled to perfection and have gone through an intense round of testing, only two smiths advance to their home forges to recreate a pair of Frankish Throwing Axes.
