Forged in Fire (2015)

S8E5 The Giant Sword of William Wallace

Four bladesmiths take on a monumental task: reducing a nine-foot dagger to precisely one-fifth of its original size. Following a series of challenging rounds that push their craftsmanship and math skills to the limit, two of them secure the opportunity to head back to their own forges and create the largest sword ever seen on Forged in Fire—the legendary William Wallace sword. As the final showdown unfolds in the testing arena, only one smith will triumph, claiming a $10,000 prize and the coveted title of Forged in Fire Champion.
