🔪Forging twisted bars of copper and steel creates a stunning layered pattern on the blade.
🔨Using a hydraulic press and rolling mill speeds up the process of shaping the blade.
🔥Heat treating the blade in multiple cycles ensures its strength and hardness.
🛡️Adding copper inlays and silver fittings enhances the visual appeal of the katana.
🖌️Crafting the handle and scabbard involves intricate shaping, engraving, and wrapping processes.
Can the twisted bars be forged into shape directly?
—No, due to the presence of copper and the risk of delamination, stock removal is necessary to shape the blade.
What is the purpose of the repeated stretching and flattening?
—The repeated process helps achieve the desired length and thickness of the blade while maintaining the layered pattern.
Why is the handle wrapped with stingray skin?
—Stingray skin provides a non-slip grip and adds a decorative element to the handle.
What is the significance of the maker's mark?
—The maker's mark represents the craftsman's identity and is a mark of authenticity and quality.
How is the blade finished to achieve its dark color?
—After applying an acid bath, the blade is treated with hot coffee to create a blackened finish.
