Forged in Fire (2015)

S3E6 Hunga Munga

Four aspiring bladesmiths are challenged to showcase their creativity by crafting a serrated blade using only the tools available on their workstations. They must extract enough steel for their creation while being careful not to melt down any essential tools they might require later. In the final showdown, the last two competitors face the task of forging a Hunga Munga, an imposing weapon that needs to have all four edges performing flawlessly through the judges' rigorous tests. Who among them will earn a $10,000 prize and the prestigious title of Forged in Fire Champion?
