Japanese Straight Sword in Manganese Steel with Black Lacquer Saya - Full Tang Ninja Ken Replica

The blade on this straight-profile ninja ken is forged from manganese steel and hand-finished to a mirror-bright chrome polish. Running a full 40.5 inches overall with a blade width of 1.26 inches, the steel carries through the entire tang without interruption - no hidden joints, no pinned construction. The needle-sharp tip and clean bevel geometry give the blade a precise, angular silhouette that stands apart from curved katana forms. Collectors interested in straight-blade Japanese sword styles will find this piece well-suited to display alongside other examples in a Manganese Sword collection.

The tsuka is built over a full tang core, wrapped first in PU black samegawa and then overlaid with tightly braided black cord in a classic diamond (hishi) pattern. The wrapping sits flush and even across the handle length, with no loose sections or uneven crossings visible. Menuki accents in dark alloy are set beneath the wrap at the traditional positions, adding subtle dimension without breaking the monochrome handle profile.

The tsuba is cast alloy in a matte black finish, shaped in a rounded quatrefoil with open cut-through sections at each lobe. The geometric design reads as both minimal and purposeful - the negative space reduces visual bulk while the thick rim maintains a solid, substantial feel in hand. Fuchi and kashira collars match in black alloy, keeping the hardware palette consistent from tip to pommel.

The saya is constructed from hardwood and finished with multiple coats of premium natural lacquer in deep gloss black. The surface shown in the product image is smooth and even, reflecting light cleanly without visible brushmarks or texture. A black-and-gold multicolor sageo - woven with orange and white accent threads - is knotted at the kurikata, providing the only deliberate color break in an otherwise all-black ensemble. Fans of straight-profile Japanese sword designs may also want to explore the Taiji Sword collection for additional display options in a similar form factor.

At 3.17 lb and 40.5 inches overall, this koshirae-style replica is proportioned for wall mounting, display stands, or shelf presentation. Package dimensions of 43.3 x 3.93 x 3.14 inches and a shipping weight of 4.4 lb reflect robust packaging appropriate for a piece at this length. The combination of chrome blade, matte black hardware, high-gloss lacquer saya, and multi-tone sageo creates a layered visual contrast that rewards close examination as a collector's piece.
