二十世紀は二度この工芸を殺しかけた。戦時の歪みと、占領下の禁令である。1948年の日刀保設立と1953年の作刀再開が刀を美術として再建し、人間国宝と無鑑査がその頂に立つ。

Documentation Documentation 鑑定書 (Kanteisho / Appraisal certificate) “Appraisal certificate.” “One sword (katana).” “Den / attribution: ‘Hasō’ (波草), Hidetada (秀忠).” (transcribed exactly as written) “Genuine. Length: 2 shaku 3 sun 8 bu (有之 = ‘recorded as such’).” “Non-profit organization: Nihon Tōken Hozon-kai (日本刀剣保存会).” “Chairman: Ōhashi Hiroshi (大橋博).” (with seal) Text (as shown): Mei: mumei (unsigned). Construction: forged; iori-mune; ubu nakago. Hamon: yakidashi present, togari-gunome. Nakago: kesho-yasurime sujikai. Mekugi-ana: one. Torokusho / Registration Text (as shown): “Firearms and swords registration certificate.” Type: katana. Mekugi-ana: 1. Mei (omote): mumei. Smith, attribution, and context The blade is registered as mumei. The kanteisho additionally records an attribution to the mastersmith: Hasō Hidetada (秀忠). Overall, it reads as practical sugata, ubu tang per the dossier, and a hamon featuring yakidashi and a strongly defined togari-gunome rhythm. Technical description of the blade (hamon → jihada → nakago → geometry/condition) 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.). The nakago is mumei, with one mekugi-ana, and is documented as ubu (生ぶ中心). The sheet specifies 化粧付筋違い (kesho-yasurime sujikai), a formal, presentational filing pattern. 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 chū-kissaki proportion. Mounting (shirasaya) 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.
