The Giant Sword of William Wallace - S8.E5

Four bladesmiths are faced with a gigantic challenge, scaling down a nine foot long dagger to exactly a fifth of its size. After a couple of intense rounds of putting their skills and calculators to the test, two competitors earn the right to return to their home forges and craft the largest sword in Forged in Fire history--the William Wallace sword. While two smiths will enter the final testing arena, only one will emerge victorious with $10,000 and the title of Forged in Fire Champion.
