Technical description of the blade
The hamon is visible and restrained, showing a regular and continuous temper line with a smooth transition between the hardened edge and the ji. Its execution is sober, consistent with practical Edo-period blades.
The overall form is that of a well-balanced tantō, with slight curvature and a clean profile. The tip is properly shaped, maintaining stable geometry.
The nakago displays an evenly developed natural dark patina. It features a single mekugi-ana. The overall condition is consistent with an old blade preserved without modern intervention.
Technical description of the koshirae
The tantō is mounted in a complete koshirae of sober and coherent design.
The saya is finished in plain black lacquer with a smooth surface.
The tsuka is wrapped in dark green tsuka-ito over samegawa, visible through the diamond-shaped openings. The wrapping shows age-appropriate wear and patina.
The menuki are small metal fittings discreetly placed beneath the wrap.
The fuchi features incised vegetal decoration with traces of gilding over a darkened ground, showing natural wear.
The kashira is metal, dark-toned, with engraved decoration and aged patina.
The habaki is a simple, single-piece example with visible file marks.
Overall, the mounting is functional, sober, and visually coherent, consistent with an Edo-period practical tantō.
