Shinto: Ryo-wazamono: Jyojyo Saku: Settsu
\nWe divide 4 sections for each sword as Saijyo Saku, Jyojyo Saku, Jyo Saku and Regular Saku.
\nThis work is ranked as Jyojyo Saku.
\nHabaki: Single-layered silver
\nBlade Length: 50.0 cm (19.69 in)
\nCurvature: 1.6 cm (0.63 in)
\nMekugi Hole: 1
\nWidth at Base (Motohaba): 3.33 cm (1.31 in)
\nWidth at Tip (Sakihaba): 2.74 cm (1.08 in)
\nThickness of Rim (Kasane): 0.73 cm (0.29 in)
\nSword Weight: 605 g
\nShape: The blade is broad with a thick kasane, and has an extended kissaki, giving it a sturdy impression.
\nIt has a relatively deep curvature.
\nOn the front side, there is a carving of a \u201cKurikara\u201d dragon entwined with a sword in grass style.
\nThe reverse side is inscribed with \u201cHachiman Daibosatsu.\u201d
\nThe carving was not done by Tadatsuna himself but by a later craftsman.
\nJigane: Finely forged ko-itame hada, resulting in a beautiful surface.
\nHamon: Nie-based gunome-midare, with a midarekomi boshi that rounds at the tip.<\/p>\n

Features: This blade is attributed to Awataguchi Omi no Kami Tadatsuna (Second Generation).
\nThe carvings on the blade were made by a different artisan at a later date, not by Tadatsuna himself.
\nHowever, the workmanship on both sides is excellent.
\nThe second-generation Tadatsuna was the son of the first-generation Omi no Kami Tadatsuna.
\nHe was commonly known as Manday\u016b and took the art name Ikkanshi.
\nHe was granted the title of Omi no Kami.<\/p>\n

Aoi Art\u2019s Comment: Claiming descent from Awataguchi Kunitsuna, a swordsmith from Kyoto in the Kamakura period, Tadatsuna’s father relocated to Osaka.
\nThe first generation Tadatsuna received the title Omi no Kami.
\nIt is said that during an incident in Edo Castle on March 24, 1784 (Tenmei 4), when Sano Zenzaemon assassinated Wakadoshiyori Tanuma Okitomo, the son of the powerful R\u014dj\u016b Tanuma Okitsugu, the weapon used was a large wakizashi made by the second-generation Tadatsuna.
\nThis event struck a symbolic blow against the notoriously corrupt Tanuma regime.
\nAs a result, Sano was revered as the “Great Deity of Restoration,” and Tadatsuna’s blades gained immense popularity.<\/p>\n

This piece resembles a katana in dimension despite being classified as a wakizashi.
\nSome of Tadatsuna’s works bear the name \u201cAsai\u201d engraved on the tang, likely indicating a connection to the Asai family.
\nIt is a splendid hira-zukuri blade, measuring a robust 3.4 cm in width, and is in excellent condition.
\nHighly recommended.<\/p>\n

Historical Background: During the Kanbun era of the Edo period, orders from samurai for swords decreased significantly, causing many swordsmiths to abandon their craft.
\nSword makers explored not only sharpness but also visual appeal to market their works.
\nThey employed various creative techniques such as flamboyant hamon, deeply set nioiguchi, beautiful jigane, and ornamental inscriptions (kinzogan).
\nWhile tantos were commonly produced during the Muromachi period, they fell out of favor in the Edo period since samurai typically carried a daisho set (katana and wakizashi) when visiting the castle.
\nThus, production of tantos became extremely rare.
\nHowever, toward the end of the Edo period, as conflict intensified, demand for tantos rose again.<\/p>\n
