Four bladesmiths are given a special assignment when they are tasked with forging Doug Marcaida's favorite blade: the Karambit. The competitors are in for twice the challenge when they must create a matching pair of the lethal knives. After Doug and the judges put these weapons through their paces, only two bladesmiths remain and return to their home forges to re-create a weapon that's both deadly and debonair: The Cane Sword. Whose blade will demonstrate that looks can kill and be handsomely rewarded with a check for $10,000 and the title of Forged in Fire Champion?
