1045 Carbon Steel Katana with Blue Piano Lacquer Saya and Purple Tsuka Ito - Full Tang Collectible Sword

This full tang katana features a 28.3-inch blade forged from 1045 carbon steel, heat-treated to 58 HRC hardness. The chrome-finished nagasa presents a clean, polished surface with a smooth transition from spine to edge. The steel composition offers a reliable balance of hardness and flexibility suited for a display-grade collectible sword.

The 10.2-inch tsuka is built on a hardwood core wrapped in white PU samegawa for texture, then finished with purple cotton ito in a traditional diamond pattern. The layered construction provides visual depth - the white same panels peek through the purple cord wrapping, creating a distinctive contrast that draws the eye along the handle.

A black alloy round tsuba sits at the junction of blade and handle, featuring a series of geometric hollow cutouts arranged in a radial pattern. A brass habaki collar with a subtle gold tone anchors the blade to the tsuba assembly, adding a warm metallic accent that bridges the dark guard and polished steel.

The 30.3-inch hardwood saya is finished in piano lacquer with a deep blue base color overlaid with delicate gold and silver wire-drawing lines. These thin metallic threads form an organic web-like pattern across the entire scabbard surface, giving it a distinctive crackled texture. A black sageo cord is tied at the kurikata, providing a clean visual anchor against the ornate blue finish.
