He studied under the 2nd-generation Sukehiro and is said to have later married Sukehiro&#8217;s sister. From Tenna 2 (1682), he began using the Tsuda surname.<br \/>\nLike Sukehiro, Sukenao produced blades with large gunome, and notare hamon. This particular work, however, is unusual in that it features a wide suguha hamon with a deep nioiguchi and abundant nie, which is thought to have been modeled after the style of Go Yoshihiro, as described in the Juyo Zufu.<\/p>\n<p>Koshirae:<br \/>\nTsuba: circular shakudo tsuba<br \/>\nFuchi: Shakudo-nanako base<br \/>\nKashira: made of horn<br \/>\nMenuki: Design of horsetails (tsukushi)<br \/>\nKozuka and Kogai: Shakudo nanako-ji, design of horsetails (tsukushi)<br \/>\nKogatana engraved with poets (Rokkasen)<\/p>\n<p>50th NBTHK Juyo Certificate<br \/>\nAoiArt estimation paper: Whole Oshigata<br \/>\nPlease note: the price does not include the shipping fees.<br \/>\n<a href=\"https:\/\/www.aoijapan.com\/img\/sword\/2026\/26443-2.jpg\"><img decoding=\"async\" src=\"https:\/\/www.aoijapan.com\/img\/sword\/2026\/26443-2.jpg\" alt=\"\" width=\"40%\" height=\"40%\" \/><\/a> <a href=\"https:\/\/www.aoijapan.com\/img\/sword\/2026\/26443-3.jpg\"><img decoding=\"async\" src=\"https:\/\/www.aoijapan.com\/img\/sword\/2026\/26443-3.jpg\" alt=\"\" width=\"16%\" height=\"16%\" \/><\/a> <a href=\"https:\/\/www.aoijapan.com\/img\/sword\/2026\/26443-4.jpg\"><img decoding=\"async\" src=\"https:\/\/www.aoijapan.com\/img\/sword\/2026\/26443-4.jpg\" alt=\"\" width=\"20%\" height=\"20%\" \/><\/a>  <a href=\"https:\/\/www.aoijapan.com\/img\/sword\/2026\/26443koshirae.jpg\"><img decoding=\"async\" src=\"https:\/\/www.aoijapan.com\/img\/sword\/2026\/26443koshirae.jpg\" alt=\"\" width=\"20%\" height=\"20%\" \/><\/a><br \/>\n<a href=\"https:\/\/www.aoijapan.com\/img\/sword\/2026\/26443paper-1.jpg\"><img decoding=\"async\" src=\"https:\/\/www.aoijapan.com\/img\/sword\/2026\/26443paper-1.jpg\" alt=\"\" width=\u201c60%\" height=\u201c60%\" \/><\/a> <a href=\"https:\/\/www.aoijapan.com\/img\/sword\/2026\/26443paper-2.jpg\"><img decoding=\"async\" src=\"https:\/\/www.aoijapan.com\/img\/sword\/2026\/26443paper-2.jpg\" alt=\"\" width=\u201c60%\" height=\u201c60%\" \/><\/a>  <\/p>\n","protected":false},"excerpt":{"rendered":"<p>Ordering Number: AS26443(Consignment Sale) Katana in Shirasaya with Koshirae (the 50th NBTHK Juyo Token) Inscription: Tsuda Oumi-no-kami Sukenao \u6d25\u7530\u8fd1\u6c5f\u5b88\u52a9\u76f4\u3000 Jyokyo Yo-nen Hachi-gatsu Hi (August 1687) \u8c9e\u4eab\u56db\u5e74\u516b\u6708\u65e5 We divide works in to Saijo Saku, Jyojyo Saku, Jyo Saku,and Regular Saku.
