🔥 Japanese Katana Crafting – The Science of Folded Steel

For centuries, the katana has captivated the world with its razor-sharp edge, graceful curve, and legendary strength. But behind its iconic beauty lies a powerful fusion of science, tradition, and human precision.

In this episode of Time Tales, we journey into the ancient Japanese forges where master swordsmiths transformed raw iron sand into blades of unmatched craftsmanship. Discover the secret of tamahagane steel, and the art of folding the blade up to 16 times — a practice that creates tens of thousands of micro-layers for strength and flexibility.

Learn how clay, heat, and water come together to create the blade’s unique hamon — not just a decoration, but a symbol of differential hardening, chemistry, and control.

From the flames of the tatara to the polishing stones that reveal the soul of the sword, every step in katana crafting tells a story of skill, spirit, and science.

This is not just a weapon. It is a legacy forged in fire.
