Four bladesmiths enter the forge and are given the twisted challenge of having to forge blades from a giant elevator cable. Which smiths will unravel after two challenges and a brutal round of testing? Only two will return home to recreate the African Ngombe Ngulu, known as the executions sword.

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.
