We divide 4 sections for each sword as Saijyo Saku, Jyojyo Saku, Jyo Saku, and Regular Saku.
This work is ranked as Jyo Saku.
Habaki: Plain copper with gold inlay (single-layer)
Blade Length: 71.2 cm (28.03 in)
Curvature: 1.9 cm (0.75 in)
Mekugi Hole: 1
Width at Base (Motohaba): 3.46 cm (1.36 in)
Width at Tip (Sakihaba): 2.40 cm (0.94 in)
Thickness (Kasane): 0.79 cm (0.31 in)
Sword Weight: 995 g

Shape:A robust blade with a wide mihaba, thick kasane, and deep curvature.
The kissaki is slightly extended.
Jigane:Well-forged ko-itame hada, forming a refined, muji-like appearance.
Hamon:Nie-deki with a rounded nioiguchi.

Features:The tang bears the inscription “Nagasone Okisato Kotetsu Nyudo”, along with a cutting test inscription stating:
“Kanbun Gannen, July 21st – San-Mitsu-Do Cutting Test, Yamano Kanjiro Shito (Kaō), Bushu.”
However, this signature is judged not to be authentic and is considered a gimei (false signature).
Despite this, the sword itself is well-constructed, with a strong and well-forged jigane.
It is also highly suitable for iaido practice due to its balance and form.

Koshirae:
Tsuba: Circular iron tsuba with stamped patterns and brass inlays.
Fuchikashira: Shakudo base with a high-relief dragonfly motif, featuring color embellishments.
