NihontoWatchNihontoWatchOur company classifies the quality of a swordsmith's work as Saijo-saku, Jojo-saku, Jo-saku, and Futsu-saku. The quality of this work is ranked as Jo-saku for a Mumei (Itakura Seki Masatoshi). Polished. Sword weight: 995 grams. Taihai: A long Naginata with Ubu nakago, featuring a solid mihaba and kasane. Jitetsu: Ko-itame hada well-grained, with some areas becoming hadatachi, resulting in a well-kneaded jitetsu. Hamon: Nie-deki gunome midare with angular gunome midare, returning with a sharp point at the saki. Tokucho: This work is Mumei but has been appraised as Sakakura Seki Masatoshi, and it is a Naginata with good taihai. A word from Aoi Art: This is a solid Naginata work appraised as Itakura Seki Masatoshi. It is a sturdy piece with a thick kasane. The Sakakura Seki were swordsmiths who began production around the Oei era in the early Muromachi period and continued until the end of the Muromachi period. I believe it is an excellent work featuring gunome midare. There is a slight thin rust on the mune. It is a Naginata from around the Eisho era of the Muromachi period; such works are few, and I highly recommend this high-quality piece. Tokubetsu Kicho Token. Aoi Art Kanteisho. Zenshin Oshigata.

Sakakura Seki Masatoshi is a name with Jūyō-designated work, and we couldn’t find current papers for this piece. Treat the name as unproven until papers say otherwise. Its older green papers are largely disavowed by the NBTHK today. — Hoshi Ask me first
