Tamahagane Steel Katana with Hamon Blade, Purple Tsuka & Black Lacquer Saya - Koshirae Style

The blade on this katana is forged from tamahagane - jewel steel produced by smelting iron sand and charcoal in a traditional tatara furnace. High-carbon pieces are selected for the cutting edge and core, while tougher low-carbon material encases them, replicating the layered construction of classical nihonto swords.

After forging, the blade undergoes clay tempering to develop a natural hamon line. Hazuya and jizuya polishing stones are applied section by section using wafer-thin slices, bringing out both the hamon and the steel's grain pattern. The result is a chrome-toned blade with a hand-finished, mirror-bright surface and a clearly defined temper line.

The tsuka is wrapped in purple cord over real white samegawa rayskin, forming the diamond-pattern characteristic of traditional koshirae fittings. A copper habaki collar seats the blade securely, and the full-tang construction runs the complete length of the handle for solid, rigid balance throughout.

A black hand-carved tsuba with an ornate scroll motif separates blade from handle, while a brown-gold braided sageo cord is tied to the saya in a layered knot - visible in the image, the dark brown and yellow braid creates a striking two-tone contrast against the black lacquered hardwood scabbard.

This katana measures 41 inches overall and weighs 3 lbs, with a 43 x 4 x 4 inch shipping package at 4 lbs.
