Alongside his pupil Taikei Naotane and the later genius Minamoto Kiyomaro, Masahide is counted among the \"Edo San-saku\" (江戸三作), the three greatest swordsmiths of Edo; a landmark exhibition marking the 200th anniversary of his death was held at the Japanese Sword Museum in 2025. This blade is signed in full and dated to Bunka 12 (1815), the height of his powers, and the tang preserves both his cursive monogram (kaō) and his stamp (kokuin) with exceptional clarity. It has been certified by the NBTHK as a \u003cstrong\u003eTokubetsu Hozon Tōken (Especially Worthy of Preservation)\u003c\/strong\u003e.\u003c\/p\u003e\n\n\u003ch3\u003eOn the smith — Suishinshi Masahide (水心子正秀 \/ Kawabe Gihachirō)\u003c\/h3\u003e\n\n\u003cp\u003e\"Kawabe Gihachirō Fujiwara Masahide\" is the full formal signature of the first-generation Suishinshi Masahide, whose name resounds through sword history as the founder of the shinshintō movement. Serving the Akimoto daimyō family, he came to believe that the swords of his own day had drifted into showy, impractical decoration, and he called for a return to the sound, functional craftsmanship of the old kotō masters of the Kamakura and Nanbokuchō periods — the fukkotō (\"sword revival\") theory. He not only preached it but wrote treatises on smithing and trained a huge school said to number more than a hundred pupils, forging robust, healthy, genuinely serviceable blades of the highest order. The year of this work, Bunka 12 (1815), falls in the mature period when his revival theory and technique had come to full fruition and his influence over the sword world was at its peak.\u003c\/p\u003e\n\n\u003ch3\u003eWorkmanship and condition\u003c\/h3\u003e\n\n\u003cp\u003eThe blade is in excellent polish, and the clarity of both ji and ha can be enjoyed to the full. The jigane is a finely, densely packed ko-nuka-hada (fine \"rice-bran\" grain), with minute ji-nie laid evenly across the surface, giving the transparent, crystalline brightness that is the hallmark of the best shinshintō work. The hamon is a ko-gunome mixed with ko-chōji and carrying a gentle notare undulation, its ko-nie forming neatly and finely along a bright habuchi. The balance of a luminous temper line and delicate, orderly activity makes for a serene, dignified result worthy of a master's hand.\u003c\/p\u003e\n\n\u003ch3\u003eForm\u003c\/h3\u003e\n\n\u003cp\u003eThis is a shinogi-zukuri katana of moderate curvature and a strong, upright presence. A handsome, powerful bōhi (single groove) is cut and kaki-nagashi on both faces of the blade; run deep and cleanly, it lends the sword crisp definition and heightens both its sculptural beauty and its air of quality. The nakago retains the signature \"Kawabe Gihachirō Fujiwara Masahide,\" accompanied by the kaō and stamp standing out sharply — a decisive document of the smith's own hand. The nagasa is 65.6 cm (about 25.83 inches, or 2 shaku 1 sun 6 bu 5 rin) with a sori of 1.67 cm (about 0.66 inch). Motohaba is a robust 33.5 mm with a thick motokasane of 9.7 mm; sakihaba 23.0 mm and sakikasane 7.3 mm. The blade alone weighs 810 g.\u003c\/p\u003e\n\n\u003ch3\u003eThe mounting (shirasaya)\u003c\/h3\u003e\n\n\u003cp\u003eThe sword is preserved in a shirasaya (plain wood storage scabbard) in excellent condition. Stripped of any superfluous ornament, the shirasaya is made to protect and display a blade's health and beauty in their finest state — the ideal way to safeguard an important sword and pass it down to future generations.\u003c\/p\u003e\n\n\u003cp\u003eSuishinshi Masahide overturned the very idea of what a Japanese sword should be and opened a new age. This is a Tokubetsu Hozon-certified work carrying his skill, his philosophy, and the weight of that history — a bright, clear jigane, a temper of quiet distinction, and the crisp kaō and stamp that are the maker's own proof. For the serious collector, a signed and dated blade by the founder of the shinshintō school stands among the most desirable of acquisitions.\u003c\/p\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Katana (刀), shinogi-zukuri\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSignature:\u003c\/strong\u003e \"Kawabe Gihachirō Fujiwara Masahide\" (川部儀八郎藤原正秀), with kaō and stamp; dated Bunka 12 (1815), a day in the 8th month — the first-generation Suishinshi Masahide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eJigane:\u003c\/strong\u003e Dense ko-nuka-hada with fine ji-nie\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHamon:\u003c\/strong\u003e Ko-gunome mixed with ko-chōji and a gentle notare, in fine ko-nie along a bright habuchi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHorimono:\u003c\/strong\u003e Bōhi (single groove), kaki-nagashi, on both faces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNagasa (blade length):\u003c\/strong\u003e 65.6 cm (≈ 25.83 in \/ 2 shaku 1 sun 6 bu 5 rin)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSori (curvature):\u003c\/strong\u003e 1.67 cm (≈ 0.66 in)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMotohaba:\u003c\/strong\u003e 33.5 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMotokasane:\u003c\/strong\u003e 9.7 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSakihaba:\u003c\/strong\u003e 23.0 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSakikasane:\u003c\/strong\u003e 7.3 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 810 g (blade only)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCondition:\u003c\/strong\u003e Excellent polish; ji and ha fully visible\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Shirasaya (plain wood storage scabbard)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCertification:\u003c\/strong\u003e NBTHK Tokubetsu Hozon Tōken (特別保存刀剣), No. 153448, dated Heisei 20 (2008)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRegistration No.:\u003c\/strong\u003e Osaka 6982\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Tozando Katana Shop","offers":[{"title":"Default Title","offer_id":53853034676587,"sku":"611-OSK006982C","price":4000000.0,"currency_code":"JPY","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0491\/2178\/8069\/files\/osaka6982_masahide_1_f1ece995-498b-440d-b6ea-d978738a77df.jpg?v=1789456355","url":"https:\/\/japanesesword.net\/products\/authentic-japanese-sword-for-sale-shinshinto-era-katana-masahide-nbthk-tokubetsu-hozon-token-certificate-tozando","provider":"Tozando Katana Shop","version":"1.0","type":"link"}
