T10 Carbon Steel Katana with Dark Red Hardwood Saya - Black-Red Handle, Hamon Blade

The blade on this katana is forged from T10 carbon steel and finished with a clearly defined hamon line visible along the length of the 40.5-inch nagasa. The chrome-polished surface catches light across the hamon's undulating boundary, showing the contrast between the harder edge zone and the body of the blade. At 1.26 inches wide and 0.275 inches thick at the spine, the geometry is consistent with traditional katana proportions. Total weight comes in at 3.17 lb.

Full tang construction runs the blade steel through the entire length of the tsuka, secured with a mekugi pin. This design keeps the handle and blade as a single rigid unit, which contributes directly to the sword's balance and long-term durability. The tang extends to the kashira, making the handle assembly structurally sound from tip to pommel.

The tsuka is wrapped in black cord over PU white samegawa, with the diamond-shaped gaps in the wrap revealing flashes of red beneath the black outer braid. The alternating black-and-red pattern runs the full length of the handle and gives the grip a strong visual identity without relying on additional ornamentation.

A round plain black iron tsuba separates the blade from the handle. The simple circular profile with no cutwork or engraving keeps the guard minimal, letting the color contrast between the dark red saya and the polished blade surface do the visual work. The fit at the habaki is snug, with a cream-toned buffalo horn habaki visible in the detail shots. For collectors interested in bold koshirae pairings, this sword fits naturally alongside pieces in our Red And Blue Katana collection.

The saya is shaped from hardwood and finished in a deep dark red lacquer that holds its color evenly across the length of the scabbard. Black sageo cord is wrapped and knotted at the kurigata in a traditional style. The overall koshirae - red saya, black sageo, black-red tsuka - forms a cohesive set. This katana is a well-defined piece for display or collection, and pairs with other bold-finish designs found in our Cool Katana collection.
