Product Details

The blade of this katana is forged from tamahagane - iron sand and charcoal smelted together in a tatara furnace following traditional Japanese technique. High carbon pieces are selected to form the cutting edge and structural core, while low carbon pieces are wrapped around the outside to add resilience. The result is a layered steel construction that reflects centuries of Japanese sword-making practice. For collectors interested in authentic materials, this piece sits within our Authentic Tamahagane Katana category.

After forging, the blade undergoes clay tempering to produce a natural hamon line along the edge. Hazuya and jizuya stones are then used to work the surface section by section, clarifying the hamon and drawing out the grain pattern of the steel. The final high-polish finish enhances every detail, giving the blade a bright, mirror-like appearance with visible activity in the steel.

The tsuka is built on a full tang foundation, wrapped first in genuine white samegawa (ray skin) and then bound with green ito cord in a traditional diamond-pattern wrap. Knot-paper inserts sit beneath the ito at the standard positions, keeping the wrap firm and properly shaped. The handle color coordinates intentionally with the dark green sageo to create a unified koshirae presentation.

The tsuba is hand-carved black iron with a raised dragon design in detailed relief. A copper habaki seats the blade cleanly at the collar, and the overall fitting set - black tsuba, copper habaki, green ito, dark green sageo - reflects a deliberate color scheme rather than an assembled mix of parts.

The saya is constructed from hardwood finished in black lacquer, fitted with a dark green sageo cord that ties through the kurikata. Overall length is 41 inches and total weight is 3 lbs, with shipping weight of 4 lbs in a 43 x 4 x 4 inch package. This is a piece built for collectors who want tamahagane materials and traditional koshirae fittings in one cohesive display sword - also listed among our Most Expensive Samurai Sword selections for those evaluating investment-grade pieces.
