Black-Wave Katana – High-Carbon Steel Japanese-Style Sword

This contemporary Japanese-style Katana combines a supplier-listed high-carbon steel blade with a black decorative surface, bright edge contrast, and a flowing wave motif. A black-and-white wrapped hardwood handle, silver-tone fittings, and matching black saya with white splatter accents create a coordinated presentation for responsible adult collection, cultural display, photography, gifting, and controlled non-contact forms after inspection.

Key Features

• Black decorative blade: A dark blade surface is paired with a bright edge line and contrasting wave motif.
• High-carbon steel: Supplier-listed high-carbon steel construction; the exact steel grade is not specified.
• Handmade presentation: Supplier-described handmade production and heat treatment.
• Removable handle assembly: The supplier lists a removable full-tang construction, although the exact nakago geometry has not been independently verified.
• Coordinated fittings: Supplier-listed brass tsuba, fuchi, kashira, and menuki with a silver-tone surface appearance.
• Patterned hardwood saya: Black finish with white splatter-style decoration and a supplier-listed silk sageo.

Specifications

Measurement note: The original 72 cm blade measurement was incorrectly paired with 27 inches; 72 cm converts to approximately 28.3 inches. The supplied blade and handle lengths total 98 cm, compared with the listed 103 cm overall length. Confirm all measurement points before activating the listing.

Blade Finish and Wave Motif

The blade features a black decorative surface with a bright cutting-line contrast and a continuous wave-shaped motif. The supplied information does not establish a natural hamon, differential hardening, or clay-tempering process, so these terms are not represented as confirmed features.

Handle and Fittings

The hardwood handle uses a black-and-white wrap over a supplier-listed ray-skin panel. The tsuba, fuchi, kashira, and menuki are supplier-listed as brass, while the photographed surfaces appear silver tone. The exact plating or surface-treatment process is not specified.

Removable Handle Construction

The supplier describes the Katana as having a removable full-tang assembly. The exact nakago length, taper, signature status, and retention configuration have not been independently documented. Owner disassembly is not recommended unless performed by a qualified person using the appropriate inspection procedure.
