It’s hammer time in the forge when four smiths have to make knives out of 10 lb sledgehammers. After the blades are smashed and bashed during a brutal round of testing, the two surviving smiths return to their home forges to recreate another iconic pounder–the Polish War Hammer. In the end, only one smith will hammer out the competition to win $10,000 and the title of Forged in Fire Champion.
