Product Details

The 28.74-inch manganese steel nagasa is the centerpiece of this katana, hardened to 62 HRC and hand-finished to a chrome-bright polish. A genuine hamon runs the length of the blade, produced through the heat-treatment process and clearly visible along the transition between edge and spine. The full tang extends the entire length of the tsuka, providing structural integrity throughout the assembly. Collectors browsing our Hand Forged Katana Sword collection will recognize the level of fit and finish applied here.

The 10.62-inch tsuka is built over real black rayskin (samegawa), which provides a textured, non-slip base layer beneath the wrap. Dark blue cotton ito is applied in the traditional diamond-lace pattern, creating evenly spaced windows that reveal the samegawa beneath. The color pairing - black rayskin against dark navy ito - gives the handle a restrained, formal appearance that complements the overall koshirae.

The alloy tsuba features a geometric lattice motif finished in a gold-and-black two-tone treatment. The cutout pattern creates depth and visual interest without overwhelming the piece, and the gold detailing at the rim frames the design cleanly against the dark ito and black saya. This tsuba sits flush within the traditional koshirae fittings, consistent with the overall assembly.

The matte black hardwood lacquer saya measures 29.92 inches and is fitted with genuine horn koiguchi at the mouth and a horn kojiri at the end cap. The matte lacquer surface absorbs light rather than reflecting it, giving the saya a quiet, understated presence against the polished blade. A dark blue sageo cord is knotted at the kurikata, echoing the ito color and completing the cohesive black-and-navy palette across the full assembly. Those looking for more options in this aesthetic can explore our Black Japanese Sword collection.

Overall, this katana measures 40.55 inches in total length and weighs 2.8 lbs. Packaged in a 42.5 x 3.9 x 3.5-inch box at a shipping weight of 3.3 lbs, it arrives ready for display or addition to a serious collection. The koshirae-style fittings - from the horn-mounted saya to the layered tsuka construction - make this a well-composed piece for collectors focused on traditional Japanese sword presentation.
