NihontoWatch月山とは出羽国月山を拠点に蝦夷の御用鍛冶として繁栄した伝統ある奥州月山鍛冶の末流です。大阪に移住して鍛刀しました。代々備前伝を得意としていますが山城伝の名作を写したものも多く残されています。天保頃の貞吉は相州伝を姿強く焼いて、貞一は五ヶ伝を上手に使い分ける器用さと、彫りの名手としても有名です。貞勝は山城伝を多く鍛えました。本刀の貞一は雲竜子と号し、大正七年七月、八十四歳で没するまで各伝上位作を狙った名作を上手に造りました。奥州月山の綾杉肌を復元して、明治三十九年には帝室技芸員となるなど名実共に一時代を築いた名工です。孫の二代貞一も人間国宝となり、現代の月山貞利は無形文化財、全日本刀匠会会長でもあります。さて本作は初代貞一の短刀となります。綾杉肌が詰んで精美な鍛に、小沸ついた直刃を焼いています。明るく冴えた匂い口には金筋は盛んに絡み見事な働きを見せています。流石は貞一の一作と感服させられます。表に八幡大神と、裏には護摩箸の彫刻が御座います。茎の状態もよく、初代貞一短刀の代表作品と鑑せられる逸品です。白鞘、ハバキは金着せ二重。

Meiji: survival after the edict
The Haitōrei edict of 1876 ended sword wearing and nearly ended the craft itself. Military demand and imperial patronage kept a remnant alive, and in 1906 Gassan Sadakazu and Miyamoto Kanenori were named Artists to the Imperial Household.
A Hozon-certified blade judged to show notably superior workmanship and a better state of preservation. The bar is higher: re-tempered blades and most unsigned Muromachi/Edo works are excluded.
The NBTHK (Nihon Bijutsu Tōken Hozon Kyōkai, the Society for the Preservation of Japanese Art Swords) is a public-interest incorporated foundation founded in 1948 and supervised by Japan’s Agency for Cultural Affairs (Bunkachō); it is based at the Japanese Sword Museum in Tokyo. Its expert panels physically examine each submitted work (shinsa) and issue a certificate (kanteishō) ranking it by artistic and historical merit. NBTHK papers are the most widely recognized standard of authentication for Japanese swords and fittings.
