Forged in Fire S05E23 - The Sawback Hunting Sword

Four bladesmiths are taken out of the forge and transported to the great outdoors, where they struggle to forge a blade in the noonday sun. They must forage for outdoor materials and crank a coal forge, which leaves some scrambling to the end. After a second smith falters during testing, the two remaining smiths return to their home forges to create the ultimate wilderness weapon: the German sawback hunting sword.
