FORGED IN FIRE

Four bladesmiths must forge a weapon using only reclaimed metal. With the clock winding down, two of the competitors are dramatically forced to improvise, and one almost doesn't make it through the round at all.

The bladesmiths must transform a steel "train spring" into a weapon of their choosing. Only two competitors will move on and are given just five days to forge a legendary Viking Battle Axe. After a barbaric round of testing from the judges, only one man will be left standing.

For this week's challenge the competitors create their signature blade by using the Hada technique--a traditional process that involves forging multiple layers of steel together. The pressure mounts as one of the smiths is pushed to his absolute breaking point.
