\nBlade Length: 71.5 cm (28.15 in)
\nCurvature: 1.73 cm (0.68 in)
\nMekugi Hole: 1
\nWidth at Base (Motohaba): 3.11 cm (1.22 in)
\nWidth at Tip (Sakihaba): 2.18 cm (0.86 in)
\nThickness of rim (Kasane): 0.75 cm (0.30 in)
\nEra: Late Edo period
\nShape: A wide and thick blade with solid construction, moderate curvature, and an extended kissaki, forming an excellent shape.
\nJigane: Fine ko-itame hada well-forged with ji-nie, forming a beautiful and dense steel surface.
\nHamon: Nioi-based gunome-midare mixed with choji-midare, consistent without flaws, and the boshi shows irregular midare patterns extending into the tip.<\/p>\n

Features:\u3000Koyama Munetsugu was born in 1803 in Shirakawa and was initially known as Sohee.
\nHe first served as a retained swordsmith for the Shirakawa-Matsudaira family but later moved to Edo and became a smith for the Kuwana domain.
\nA considerable number of his works remain, all of which are of high quality, with virtually no inferior pieces.
\nNotably, there are no examples of poorly forged blades, and his surviving works demonstrate excellent craftsmanship.
\nHis style is characterized predominantly by gunome-midare with a boshi that enters in midare-komi (irregular patterns into the tip).
\nHis style is similar to that of Nagatoshi Tsunatoshi, though Tsunatoshi’s hamon typically has bifurcated heads in the gunome patterns\u2014a trait not found in Munetsugu\u2019s work.
\nAlso, Munetsugu\u2019s boshi always features midare-komi; if one encounters a perfectly rounded boshi, the signature should be questioned.
\nAside from that, the stylistic similarity suggests a very close relationship between the two.
\nAnother of his consistent traits is his unwavering adherence to gunome-midare throughout his work.
\nHe had older brothers named Koyama Munetaira and Munitoshi, whose works also share similar stylistic elements.
\nIt is assumed that he must have regretted being forced to abandon swordsmithing due to the Haitorei Edict of 1876.
\nThis sword is a Jyojyo Saku-level work among the Shinshinto category and strongly resembles the Sue-Bizen style\u2014particularly that of Osafune Yosazaemon no Jo Sukesada\u2014demonstrating Munetsugu\u2019s remarkable success in faithfully recreating the Sue-Bizen tradition.<\/p>\n

Koshirae:
\nTsuba: Iron tsuba in a rounded square shape (nadeshiko-gata), carved with a dragon motif and decorated with gold iroe (colored metalwork).
\nFuchikashira: Shakudo nanako-ji base, carved with a dragon design and adorned with gold iroe.
\nMenuki: High-relief carving of a dragon motif, finished with gold iroe.
\nSaya (Scabbard): Vermilion lacquered saya.<\/p>\n

Aoi Art\u2019s Comment:\u3000This sword has a wide body with an extended kissaki and excellent overall shape, complemented by a remarkable hamon.
\nIt is a piece forged during the Tenp\u014d era, considered the peak of Koyama Munetsugu\u2019s swordsmithing career.
\nThe cutting test inscription \u201cat Senju, Taidai Dotanbari\u201d is also of great value.
\n\u201cTaidai\u201d refers to the region around the shoulder blades, while \u201cDotanbari\u201d indicates the severing of both the body and the supporting platform.<\/p>\n

Historical Background:\u3000In 1867 (Kei\u014d 3), the Tokugawa shogunate returned power to the emperor, ushering in the Meiji era the following year.
\nThe Haitorei Edict banning the wearing of swords was issued in 1871.<\/p>\n
