S5E23 The Sawback Hunting Sword

Four bladesmiths step away from their usual forges and venture into the great outdoors, where they face the challenge of crafting a blade under the blazing sun. They must gather materials from their surroundings and operate a coal forge, leading to a frantic race against time. When a second smith fails during the testing phase, only two remain to head back to their home forges. Their task is to create the ultimate weapon designed for survival in the wild: the German sawback hunting sword.
