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.

Four bladesmiths must forge a fully functional serrated knife using steel from hand scissors, or risk getting cut from the competition. Serrations prove to be more than just a bump in the road for the two smiths who don't make the cut. The remaining two competitors return to their home forges to create a unique and challenging weapon from history: the Sengese.
