0.00 57 minutes Japanese swords fascinate collectors around the world. A special kind of steel called tamahagane is required to make them. This miraculous material is strong, flexible, rust-resistant, and produced through the ancient process of "tatara" ironmaking which takes place over three days and nights. Due to the COVID pandemic, there was only one production run in 2022, which was hit by a series of problems. Did the team meet the challenge? This documentary captures the essence of Japanese craftsmanship.
