Forged in Fire S04E14 - The Kachin Dao

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.
