This blade is 'shinogi zukuri', has a shallow curve and a small 'kissaki'. The unmodified tang has one hole and the file markings are 'kesho' with 'osujigai'. The grain is almost indiscernible, closely packed 'koitame'. The 'hamon' is an even 'suguha' in 'nie' with a tight 'nioiguchi'. The 'boshi' is 'komaru' with a somewhat pointed return.
This blade was the joint endeavour of Tsunatoshi and Koretoshi, who were father and son. Chojusai (originally Chounsai) Tsunatoshi (d. 1863) was the son of Kato Kunihide who studied under Suishinshi Masahide. Together with his brother Tsunahide, he moved from his native Ushu (Dewa) Province to go to Edo. His pupils include Unju Korekazu (see no. 67). In 1856 he gave the name Chounsai to his son Koretoshi, and assumed the name Chojusai. The habaki is comprised of a single piece, and has gold cladding.
The scabbard has designs of plum blossoms formed from ray fish skin inlaid into black lacquer and polished flat. The 'fuchi', 'kashira' and 'menuki' have scenes from the Gempei wars in 'shakudo' with high-relief coloured metal inlay. The iron 'tsuba' has similar scenes pierced and roundly carved, with details in gold inlay.
