(We divide 4 sections for each sword as Saijyo saku, Jyo-jyo saku Jyo saku and regular saku)
This sword belongs to Jyo Saku ranking.

Habaki:Silver and gold foiled double Habaki.
Blade Length: 61.1 cm (24.05 in)
Sori (Curvature): 1.4 cm (0.55 in)
Motohaba (Width at Base): 3.12 cm ( 1.22in)
Sakihaba (Width at Tip): 2.06 cm (0.81 in)
Kasane (Thickness): 0.77 cm ( 0.30 in)
Mei (Signature): 1 hole
Weight: 600 grams
Era: Muromachi period, August, 10th Year of Eisho Era
Shape: This sword possesses a moderately wide body and substantial kasane, featuring a gently curved edge suitable for one-handed use during its time.
Hada (Grain Pattern): It displays a finely forged ko-itame hada with well-defined lines.
Hamon (Temper Pattern): The hamon exhibits a notare-style pattern with ashi (feet) and yubashiri (clove-shaped lines) appearing within the temper line, and sunagashi (flowing
sand-like lines) and nijuba (double temper lines) with kin-sugi (golden lines) in the ha (blade edge). The boshi (temper pattern at the tip) is midare-komi (irregular).

Features: Bishu Nagafune Sukemasa’s works from the Eisho period are known for their high quality. However, towards the end of the Muromachi period, the quality of swords produced began to decline. This particular piece is well-crafted, with a single mekugi-ana(peg hole) that is securely made.

From Aoi Art: I believe that this sword, designed for one-handed use, became more prevalent as combat methods transitioned to battlefield warfare. The fine hada and well-executed hamon make this an exceptional piece that I highly recommend.
