1045 Carbon Steel Katana with Blue-Black Printed Blade in Dark Blue Tsuka and Black Saya

The blade on this katana is the first thing that stops you - a full-length blue-black printed surface applied over 1045 carbon steel, producing a fragmented, crystalline visual effect that shifts tone from deep navy at the spine to vivid teal near the edge. The steel itself is ground to a consistent profile measuring 1.259 inches at the base, tapering cleanly toward the tip, with the hand-finished edge running the full nagasa. At 40.15 inches overall and 2.8 lb, the balance sits comfortably forward without feeling unwieldy. Collectors interested in bold blade aesthetics will find this sits naturally alongside other pieces in the Blue Printed Blade Katana category.

The full-tang construction is a defining structural detail - the steel extends uninterrupted through the entire length of the tsuka, bonded beneath the wrapping rather than pinned at a shallow depth. This gives the handle its solid, non-flexing feel when held. The tsuka itself is wrapped in dark blue ito over PU white samegawa, the cord pulled into clean diamond windows that reveal the pale imitation ray skin at regular intervals down the grip.

The tsuba is cast black iron worked into a cloud scroll pattern - curved, layered forms that repeat around the full circumference of the guard. It sits against a gold-tone habaki, a pairing that introduces warmth against the otherwise cool and dark color palette of the sword. The seppa washers on either side of the tsuba are finished in a light cream tone, adding a subtle layering detail at the transition point between blade and handle.

The saya is built from hardwood and wrapped in black PU leather, giving it a smooth, consistent surface that complements the blade's dark tones without competing with them. A dark blue sageo cord is threaded through the kurigata, finished with an amber-colored bead toggle that provides a single warm accent against the black sheath. The sageo color deliberately echoes the tsuka ito, tying the upper and lower components of the koshirae together visually.

As a 1045 Carbon Katana replica, this piece is designed for collectors who want a visually distinctive sword with cohesive construction across every component. Overall dimensions: 40.15 in length, 1.259 in blade width, 0.275 in thickness, 2.8 lb. Shipping weight 3.3 lb, packaged at 42.9 x 3.9 x 3.5 inches.
