A rare kata-mei kiwame (authenticated signature) piece with a majestic presence exceeding a nagasa of 2 shaku 7 sun, attributed to the representative Satsuma swordsmith, Mondenoshō Masakiyo. The jigane is a finely packed ko-itame mixed with oh-itame, covered in rich ji-nie. The hamon is a gorgeous and spirited notare-style gunome-midare with deep nie and nioi. The ha-buchi features magnificent kinsuji and sunagashi, resulting in a masterpiece-quality finish. The tsuka of the koshirae is tight, making it difficult to seat the toshin perfectly. It should fit properly with minor adjustments, such as slight shaving. Mondenoshō Masakiyo was a swordsmith of Satsuma Province during the Edo period. He is ranked as Shinto Saijo-saku (top-tier) and Oh-wazamono (great sharpness). In the 6th year of Kyoho, he forged swords in Edo by the command of the 8th Shogun, Tokugawa Yoshimune. 0 Yen (Tax included)

The Satsuma school gathered the smiths of southern Kyushu under the patronage of the Shimazu, the daimyo house of Satsuma and Osumi, and the published sources read its history in two distinct flowerings rather than one continuous line. Its shinto fountainhead is Izu no Kami Masafusa, a son of the Mino smith Ujifusa who moved to Kagoshima and carried a strongly nie-laden hand into the province; the NBTHK names him the origin of Satsuma forging.
