[ Feature ]

Engraving : The engraving depicts a sanko-ken trident-hilted sword on the front.
Nakago : Ubu nakgo raw tang, shallow file marks with a natural taper, chestnut-shaped tip, one mekugi hole.
Jigane : The jigane has a slightly mokume-grain texture and ji-nie.
Hamon : The hamon is a nioi pattern, straight and well-forged, mixed with chouji and mutsu-me patterns, and well-defined ashi.
Boushi : The boushi is a small, rounded tip with a disordered finish.

[ Highlight ] The blade exhibits a pleasing form with a well-balanced curvature and a good width difference between the base and tip. The jigane is a fine, clean ground with a good mokume-grain pattern. The hamon, a beautiful nioi pattern with chōji elements, features the unique chōji-style blade pattern that this smith specialised in – a complex combination of irregular heads resembling tea flowers. Yūei's engraving is rare, making this a valuable piece of fine work that harmonises well with the overall atmosphere. Yokoyama Sukenaga had a first and second generation, both receiving the title of Kaga-no-suke. The first generation was the second son of Sukesada (Yūhei), inheriting the Yūhei lineage after his elder brother Sukemori became an adopted son of the Shichibei family. Works exist with signatures that indicate the first generation was the 56th descendant of Tomonari and the second generation was the 57th descendant of Tomonari. The first generation's dated works include: Tenmei 6 (1786), Bunka 10 & 12 (1813 & 1815), Bunsei 3, 7, 8, 9, 10, 11, 12, 13, 14, 15 (1820-1833), Kōka 2, 3, 4 (1845-1847), and Kaei 2, 3 (1849-1850). The second generation's dated works include: Kaei 3, 5, 6 (1850, 1852, 1853), Ansei 2 (1855), Man'en 1 (1860), and Genji 1 & 2 (1864-1865).
