Скачать или смотреть Inside the Japanese Sword Factory – How Katanas Are Forged From Iron Ore to Final Cut Test

Step inside a traditional Japanese sword forge and discover the complete process of how katanas are made from raw iron sand to final cutting tests. This documentary-style video reveals the ancient workflow spanning 90 days, from smelting iron ore in a traditional tatara furnace, forging tamahagane steel through 15 folds creating 32,768 layers, shaping the blade, applying clay for differential hardening, dramatic water quenching, mirror polishing, mounting the handle with ray skin and silk wrapping, and ultimate test cutting demonstrations.
Watch how master swordsmiths and apprentices use centuries-old techniques to produce legendary Japanese blades. You will see the entire sword-making process in action, including three-day continuous steel smelting, rhythmic hammer forging, precision grinding, traditional clay tempering, explosive quenching creating the curved blade and hamon line, meticulous hand polishing with natural stones, custom handle wrapping, and tameshigiri cutting tests on straw mats and bamboo.
This full process shows how black iron sand is transformed into a razor-sharp functional katana through fire, water, and hundreds of hours of dedicated craftsmanship. The video highlights how traditional methods, master knowledge, and physical skill combine to create swords that are both deadly weapons and museum-quality art pieces.
Whether you love Japanese culture, martial arts, blacksmithing, metallurgy, or factory documentaries, this is a complete look inside the ancient craft of Japanese sword making.
