Blue-Black 1065 Steel Tachi – Lacquered Wood Saya

The LOONGSWORD Blue-Black 1065 Steel Tachi is a modern Japanese-style collectible sword featuring a 28.3-inch Shinogi-Zukuri blade, Tachi-inspired mounting and a lacquered wood saya. Its blue-black blade finish, copper guard and black-over-red handle treatment create a distinctive presentation for adult collectors and cultural display.

Key Features

• 1065 High-Carbon Steel Blade: Quenched and treated with controlled-temperature tempering according to the supplied manufacturing specification.
• Blue-Black Surface Finish: The blade receives a separate blued surface treatment after heat treatment. This coloration is not a natural hamon or clay-tempered pattern.
• Shinogi-Zukuri Geometry: A defined ridgeline and traditional Japanese-style blade profile give the Tachi its structured appearance.
• One-Piece Full Tang: The blade extends through the handle and is secured with supplier-specified bamboo mekugi.
• Tachi-Style Materials: Copper tsuba and habaki, brass seppa, black cotton ito over red genuine ray skin, and genuine silk sageo.
• Lacquered Wood Saya: A wooden scabbard with a high-hardness lacquer finish and supplier-listed wooden kurikata and koiguchi components.

Specifications

Materials and Construction

The 1065 high-carbon steel blade uses a one-piece full-tang structure secured by bamboo mekugi. The supplied heat-treatment specification combines muffle-furnace heating, quenching and controlled-temperature tempering. No hardness value has been supplied, so no HRC or cutting-performance claim is made.

Finish clarification: The blue-black appearance is a surface treatment and is separate from the blade’s heat treatment. It is not a natural hamon, clay-tempered pattern or corrosion-proof coating. Color depth may vary slightly under different lighting and normal handling.

Tachi-Style Presentation

The mounting references the visual language of classical Tachi koshirae, pairing an ornamental copper tsuba with a lacquered wood saya and silk sageo. This is a newly manufactured Japanese-style collectible and is not presented as an antique or Japanese-certified Nihontō.
