The contestants are up against the fan favourite Forged In Fire flex test! Doug Marcaida gives these blades a whirl before David Baker bends them till we (and they) can't take any more. Did you watch this from behind your hands like us? Each week, four of the best bladesmiths 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.
