~ The papers attribute this sword to 16th century TSUNAHIRO. There are three generations of TSUNAHIRO that worked in the 16th century. ~
TSUNAHIRO SHODAI [TENMON 1532 SAGAMI] SUEKOTď JďSAKU
His family name is Yamamura, and in the beginning his mei was Masahiro. He was later beckoned by H˘j˘ Ujitsuna of Odawara, was granted the use of one kanji, and changed his signature to Tsunahiro. His legal name was the G˘ of Tsuramuki and is said to have been granted the title of Taima no Kami, but this is not clear. His works have horimono of kenmakiryű, bonji, suken nado, hamon is midare ha or hitatsura ha. (Ry˘wazamono)
TSUNAHIRO SďSH█ NIDAI [EIROKU 1558 SAGAMI] SUEKOTď JďSAKU
His family name is Yamamura, he is called Taima, legal name was the G˘ of Munemoto. His works are predominantly wakizashi, hamon has midareba, hitatsura, suguba nado, and has horimono of kenmakiryű and kusa no kurikara.
According to a genealogy chart of the house of Yamamura and old documents, a change of ownership between the first and second generations can be seen between Tenmon 7 to 10 and there is a theory that these old documents are not accurate, and that the first and second generation are the same person, but they are written according to an outline of Yamamura family documents.
TSUNAHIRO SďSH█ SANDAI [BUNROKU 1592 SAGAMI] SUEKOTď JďSAKU
He is called Yamamura Souemonnoj˘, and lived in Kamakura ďgigaya. Later, at the beckoning of the Lord of the Tsugaru Han he moved, and made three hundred daish˘ katana. He finished this enterprise in Keich˘ 11 and returned to his home kuni. His works are many, hamon is midare ha, hitatsura and suguba ko-midare ha, and there are also horimono. He died on the 27th day of the second month of 9th year of Kan'ei, at the age of 91.
This Katana was attributed to 16th Century Tsunahiro. There were three generations and it is difficult to know the exact smith amongst these three that made this sword. They all made Hitatsura hamon. In anycase they are all highly rated smiths of the soshu tradition.
This sword has an abundance of activity all over the blade and has a full hardened kissaki. The hada has some course hada and some in the shinogi-ji. No flaws are visible on this old sword and is very interesting. Hitatsura is very desirable to many collectors as is Soshu den work.
