Ordering Number: AS25816
\nKatana in Shirasaya with Koshirae (28th Juyo Token)<\/p>\n

Signature: Bishu Osafune Sukesada (Hikobei no Jo Sukesada)
\nA day in February, Eisho 6 (1509)
\n\u5099\u5dde\u9577\u8239\u7950\u5b9a(\u5f66\u5175\u885b\u5c09\u7950\u5b9a)
\n\u6c38\u6b63\u516d\u5e74\u4e8c\u6708\u65e5<\/p>\n

Sayagaki: Tanobe Sensei.
\n28th Juyo Token, Bizen Osafune Sukesada.
\nThis work bears the sixth-generation style signature and dates to the Eisho 6 (1509) period.
\nAlthough it lacks a secular name, it is a carefully made work.
\nIt is probably by Hikobei no Jo, the father of Yosazaemon no Jo.
\nThe blade is slender with deep curvature, giving at first glance the impression of a tachi-style shape, though the curvature toward the tip reveals characteristics of the period.
\nThe forging shows well-refined itame and presents a delicate and exquisite surface texture.
\nThe hamon is based on koshi-biraki gunome midare, mixed with choji, pointed temper, and double gunome, creating a lively pattern.
\nThe nioiguchi is tight, bright, and clear, and the boshi forms a pointed midare-komi style, making this an outstanding work.
\nAt the base there are carvings of a grass-style Kurikara dragon and incised sacred characters, along with bonji carvings.
\nThese carvings are skillfully executed.
\nIt is noteworthy that many inscriptions with deep carvings among the Sukesada father and son works do not include secular names.
\nBlade Length: 2 shaku 2 sun 5 bu han.
\nWritten by Tanzan (kao).<\/p>\n

(We divide 4 sections for each sword as Saijyo Saku, Jyojyo Saku, Jyo Saku and Regular Saku).
\nThis work is ranked as Saijyo Saku (highest grade) among works by Bishu Osafune Sukesada.
\nHabaki: Gold foiled double habaki.
\nBlade Length: 68.3 cm (26.89 in).
\nCurvature: 2.8 cm (1.10 in).
\nMekugi Hole: 1.
\nWidth at Base (Motohaba): 3.0 cm (1.18 in).
\nWidth at Yokote: 2.1 cm (0.83 in).
\nThickness of rim (Kasane): 0.54 cm (0.21 in).
\nSword Weight: 615 g.
\nEra: A day in February, Eisho 6 (1509).
\nShape: A katana made for one-handed use.
\nOn the front side are carvings of a tokko (vajra) and a grass-style dragon, and on the reverse side the inscription \u201cHachiman Daibosatsu\u201d and bonji characters are carved.
\nThe blade has deep curvature and an extended kissaki, giving it an excellent overall shape.
\nJigane: The jigane is tightly forged, with utsuri appearing, resulting in a very refined steel surface.
\nHamon: Nioi-deki with a magnificent choji midare.<\/p>\n

Features: As you may know, inscriptions including a secular name began from the period of Hikobei Sukesada onward, and it is believed that such names did not exist before this time.
\nPlease particularly note these carvings.
\nFurthermore, the finely detailed midare hamon, the utsuri, and the dynamic midare-komi boshi together form a truly remarkable temper pattern.
\nThese points are described in detail by Tanobe Sensei on both sides of the sayagaki.
\nTanobe Sensei identifies the smith in the sayagaki as Hikobei Sukesada, the father of Yosaemon Sukesada.<\/p>\n

Aoi Art\u2019s Comment: This is a magnificent work with splendid choji midare and a boshi that turns dynamically into midare-komi.
\nBlades that show utsuri and also feature such superb carvings on both sides are extremely rare.
\nIt is likely that this is a top-class work produced on special order for a daimyo.<\/p>\n

28th Juyo Token.
