    Mei (omote): mumei.<\/p>\n

     <\/p>\n

    Smith, attribution, and context<\/strong><\/p>\n

    The blade is registered as mumei. The kanteisho additionally records an attribution to the mastersmith: Has\u014d Hidetada (\u79c0\u5fe0).<\/p>\n

    Overall, it reads as practical sugata, ubu tang per the dossier, and a hamon featuring yakidashi and a strongly defined togari-gunome rhythm.<\/p>\n

    Technical description of the blade (hamon \u2192 jihada \u2192 nakago \u2192 geometry\/condition)<\/p>\n

    The hamon is clearly visible as togari-gunome (repeating pointed peaks) with yakidashi at the machi, matching the technical sheet. Fine activity (nie\/nioi, sunagashi, etc.).<\/p>\n

    The nakago is mumei, with one mekugi-ana, and is documented as ubu (\u751f\u3076\u4e2d\u5fc3). The sheet specifies \u5316\u7ca7\u4ed8\u7b4b\u9055\u3044 (kesho-yasurime sujikai), a formal, presentational filing pattern.<\/p>\n

    Regarding geometry, based on documentation and visual reading: shinogi-zukuri katana with iori-mune, nagasa 72.0 cm and sori 1.8 cm. The kissaki shows a clear yokote in the full-length shots, consistent with a ch\u016b-kissaki proportion.<\/p>\n

    Mounting (shirasaya)<\/strong><\/p>\n

    The sword is housed in a light-wood shirasaya (storage mounting). For a blade of this profile, shirasaya is not a mere accessory: it is the correct solution for long-term preservation, stable storage, and a sober, collector-grade presentation.<\/p>\n
