Forged in Fire

The Kachin Dao (4x14)

:

This competition isn't smooth sailing as the four bladesmiths must use steel from old nautical equipment to forge weld their signature blade, while being forced to do it using a metal inlay technique. After two turbulent rounds, two smiths propel to the final round where they have just five days to forge the Kachin Dao, a deadly headhunting sword. It's sink or swim as only one can rise above the tide to be named the Forged in Fire Champion.
