The judges challenge this week's contestants with building some of the deadliest weapons from history. Are they up for the challenge, or will they crumble under the pressure? Each week, four of the best blade smiths in America put both their skills and reputations on the line. The competition is fierce. In the first two rounds, contestants face-off, forging blades they hope can withstand the judges’ grueling tests. Only two smiths will be left standing and continue on to the final round where they’ll have to put it all on the line and create a historic blade. It takes a certain mix of brains and brawn to be crowned the Forged in Fire champion.
