Forged in Fire: The 12 Cuts of Christmas

Four bladesmiths test their mettle in a rock quarry, where they're tasked with making blades using harvested steel and coal forges; the smiths construct a blade while fighting the elements; the remaining two smiths must re-create the Spanish Navaja.

The bladesmiths are tasked with creating a signature Damascus blade out of three different steels of different thicknesses; the two final competitors re-create one of the most intricate weapons in show history: the steel crossbow.

Four bladesmiths get to pick their mild steel to make a san mai blade, but the easier their choice, the more difficult their high carbon steel will be; the smiths who survive the testing then return home to re-create the Belgian Walloon sword.
