shows characteristics of the Bizen-den style with choji-midare hamon, clearly demonstrating its features.<br \/>\nBlade length: 1 shaku 4 sun 2 bu.<br \/>\nInscribed by Tanzan Hendo Kan (Kao).<\/p>\n<p>Shinshinto: Saijyo Saku: Musashi Province<br \/>\nWe divide 4 sections for each sword as Saijyo Saku, Jyojyo Saku, Jyo Saku and Regular Saku.<br \/>\nThis work is ranked as Jyojyo Saku (second highest) for Chikuzen Daijo Fujiwara Naotane.<br \/>\nHabaki: Single-layered, silver<br \/>\nBlade Length: 43.2 cm (17.01 in)<br \/>\nCurvature: 1.3 cm (0.51 in)<br \/>\nMekugi Hole: 1<br \/>\nWidth at Base (Motohaba): 2.53 cm (0.99 in)<br \/>\nWidth at Tip (Sakihaba): 1.66 cm (0.65 in)<br \/>\nThickness of Rim (Kasane): 0.52 cm (0.20 in)<br \/>\nSword Weight: 280 g<br \/>\nEra: Late Edo period, 1847 (Koka 4)<br \/>\nShape: The blade has a slightly narrow width and thickness, with an elegant shape typical of Naotane&#8217;s wakizashi.<br \/>\nJigane: Itame-hada well-forged with visible grain and ji-nie.<br \/>\nHamon: Choji-midare.<br \/>\nA bright and clear hamon with deep ashi and thick nioiguchi.<br \/>\nThe boshi is deeply notched and returns in a small round shape.<\/p>\n<p>Features:\u3000Taikei Naotane was born in Dewa province and known as Shoji Minohyoe.<br \/>\nHe studied under Suishinshi Masahide and served under Lord Akimoto with his master.<br \/>\nIn Bunsei 4 (1821), he was granted the title of Chikuzen Daijo.<br \/>\nLater, he moved to Edo and re-entered Masahide\u2019s school, mastering Bizen-den, Soshu-den, Mino-den, and Yamato-den.<br \/>\nWhile Masahide promoted the revival of kot\u014d styles, Naotane forged his own unique path by producing jigane with swirling patterns, creating works quite distinct from his master.<\/p>\n<p>Koshirae:<br \/>\nTsuba: Plain copper base with engraved bird design, decorated with gold inlay.<br \/>\nFuchikashira: Plain copper base with high-relief carving of deer motifs, decorated with gold inlay.<br \/>\nSaya: Glossy black lacquered saya (kuro-roiro).<br \/>\nMenuki: High-relief carvings of locusts and dragonflies.<br \/>\nKogai: Shakudo nanako ground with floral motif in high relief, decorated with gold and silver inlay.<br \/>\nKozuka: Shakudo nanako ground with floral motif in high relief, decorated with gold and silver inlay.<br \/>\nWith kogatana (small knife).<\/p>\n<p>Aoi Art\u2019s Comment:\u3000Taikei Naotane is one of the most renowned smiths of the late Edo period, excelling in Bizen-den, Soshu-den, Mino-den, and Yamato-den.<br \/>\nWorks engraved with the \u201cOshiteru\u201d mark are rare.<br \/>\n\u201cOshiteru\u201d is a pillow word for Naniwa (Osaka), meaning he was based in Osaka.<br \/>\nThis piece is a long and deeply curved reproduction of a kot\u014d-style blade.<br \/>\nIt is a work that might be mistaken for a copy of Ko-Bizen or Kuniyuki.<br \/>\nI once saw an Important Art Object by Naotane in the Soshu-den style, and it was outstanding.<br \/>\nThis piece also resembles kot\u014d works and is highly recommended.<br \/>\nAs the Bakumatsu period approached, iron quality gradually improved through the Bunka, Bunsei, and Tenpo eras.<br \/>\nAnticipating increasingly intense warfare, domains began to demand more swords.<br \/>\nIt is believed this led to greater efforts to produce superior blades.<\/p>\n<p>NBTHK Tokubetsu Hozon Token<br \/>\nAoi Art estimation paper<br \/>\nWhole Oshigata<\/p>\n<p>Please note: the price does not include the shipping fees.<\/p>\n<p><a
