An exceptionally rare Katana\u2014seldom seen even in top-tier domestic auctions\u2014combining scarcity with remarkable quality in both Hamon and Jigane.<\/span><\/strong><\/p>\n

 <\/p>\n

Forged by Tsukushi Nobukuni, a distinguished group of swordsmiths who blended the refined elegance of the Kyoto Nobukuni school with the robust strength of Kyushu craftsmanship.<\/span><\/strong><\/p>\n

 <\/p>\n

Very few of their works survive today, making any existing piece highly valuable\u2014and this one is made even more extraordinary by the dragon carving engraved on the blade, an almost unheard-of feature in Nobukuni swords.<\/span><\/strong><\/p>\n<\/div>\n<\/div>\n<\/div>\n

          Katana Certificate of Authenticity and Registration<\/h2>\n

          \"\"<\/p>\n

          Based on a comprehensive evaluation of every detail and element of craftsmanship, we can confidently state that this Katana is not only a \u201cReal Katana,\u201d but also an\u00a0\u201cAuthentic Katana\u201d<\/strong>\u00a0of exceptional historical value. For the definition of an Authentic Katana, please refer to this page.\uff08\u2192\u00a0What Makes A Katana Real<\/a>\uff09<\/p>\n

           <\/p>\n

          \"\"<\/p>\n

          This Katana has been certified as a\u00a0Tokubetsu Hozon Token (\u7279\u5225\u4fdd\u5b58\u5200\u5263)<\/strong>\u00a0by the NBTHK (Nihon Bijutsu Token Hozon Kyokai), a prominent organization in Japan dedicated to the preservation of Japanese swords. This title is awarded to swords that are considered to be of high craftsmanship and in good preservation condition.\u00a0It ranks above the regular Hozon Token(\u4fdd\u5b58\u5200\u5263) certification, indicating a higher level of appraisal.\u00a0(The official certificate paper is included in the set.)<\/p>\n

          While NBTHK certification is a respected standard and provides a helpful indication of quality and authenticity, it should not be viewed as a definitive measure of a sword\u2019s true value. In reality, many swords are able to obtain certification if they meet certain criteria, meaning not all certified swords are particularly rare or exceptional. Conversely, some outstanding swords remain uncertified simply because their owners have not submitted them for evaluation.<\/p>\n

          That said, being recognized by Japan\u2019s most established sword appraisal organization does provide a useful baseline, and can serve as a reassuring point of reference when considering a sword.<\/p>\n

           <\/p>\n

          \"\"<\/p>\n

          All Real Katanas are officially registered with the Board of Education of the prefecture in which they are located, and each comes with a registration certificate. This Katana also comes with its registration certificate, as shown in the attached image.<\/p>\n

          The original certificate must be returned to the Board of Education prior to export, but we will provide a copy of the certificate along with your purchase.<\/p>\n

          Each part of the Katana<\/h2>\n

          1. Toshin(\u5200\u8eab)<\/h3>\n

          \"\"<\/p>\n

          The Toshin<\/em> refers to the entire blade of the Katana.<\/p>\n

          When evaluating a Katana, the blade\u2019s length\u2014and particularly its sori<\/strong> (curvature)\u2014is a key point of appreciation.<\/p>\n

          The sori<\/em> is what enables the Japanese sword to remain unbreakable and unbendable, while also allowing it to cut through objects with remarkable efficiency and minimal force.<\/p>\n
