Forjado a fuego

Four smiths turn a pile of rusty old nails into a pristine knife. After their weapons are hammered in testing, the two surviving competitors return home to recreate the terrifying North African Tuareg Takoba. When they return to the forge, another brutal round of tests will determine which smith really hit the nail on the head and will win $10,000 and the title of Forged in Fire Champion.
