The sword has an overall length in the scabbard of approximately 39 inches, with a blade length of approximately 25-1/2 inches. The blade is generally bright,with a visible flowing temper line and it is without chips, nicks, or active rust. The sword tang is dated in February of 1870 and it is signed “Made by Gassan Minamoto Sadakazu”, who was a “jōjō-saku”, meaning a swordsmith who was ranked as “Highly Superior”, just below the highest rating of “saijō-saku“, or “Grand Master”. The tang also has a hot-stamp at the bottom is a stylized part of his name, “Sada”. Sadakazu was born in 1836. His actual name was “Gassan Yagoro”. The ray skin grip is wrapped in the traditional style with golden brown fabric that shows staining from repeated handling in the field. Beneath the wrapping are the traditional military menuki of three cherry blossoms on each side. The brass tsuba guard is the solid brass style with relief cherry blossoms. The scabbard of the sword retains most all of the olive brown paint, showing some minor scuffs. Overall excellent condition. This listing includes a photograph of swordsmith Sadakazu from the reference book “Japanese Swordsmiths” by Markus Sesko. A copy of the photograph is not included with the sword.
