About this Katana blade:

The original documentation (NBTHK) testifies to the authenticity in terms of being an ancient Nihonto Kanana blade from the Shin-to period and being the authentic signature Kanenaga, but the School remains undefined which, according to various studies, may be the Dōtanuki (同田貫) or the Tegai .
My personal opinion which is supported after consultation with a member of the Japanese NTKK and also with the family origin information of the former Japanese owner due to the characteristics of the blade, the very prestigious Dōtanuki school (同田貫) with a small number of forgers that has a known origin in the mythical Enju Kunimura (延寿 国村) seems most likely.

Also the other Japapanese original documentation the card (Kyoiku-inkai) reproduces the signature (Mei) of the Nakago as a precise identification of belonging.

It is an aesthetically very slender and beautiful blade, but it proves to be very strong and resistant, something typical of a good battle Katana blade made in its time for real use in combat.


The Dōtanuki battle swords:

The Dōtanuki 同田貫 School evolved in Higo Province, with its roots traced back to the famous "Enju Kunimura" (延寿国村). Enju Kunimura founded the Higo Enju school in 1305. Kunimaura was born in Yamato province, the son of swordsmith (tosho) Hiromura. He migrated to Yamashiro province, became a student of Rai Kuniyuki, and later married Kuniyuki's daughter. Kunimura later migrated to Higo and founded the Enju school. Only six Kunimura blades are known to exist.
The Dotanuki school emerged in the small village of Higo in the mid-16th century, making do with Enju's blacksmiths and masters when Enju closed at the end of the Koto period. The founder of the Dotanuki school was Dotanuki Masakuni, he was called Oyama Kozuke no Suke although his original signature (before Dotanuki) was Nobuyoshi. The famous General Katō Kiyomasa granted Masakuni the honor of using a character (kanji) of his name, and Nobuyoshi was known as Masakuni ever since.
Dotanuki swords quickly gained great popularity among the warrior class, due to their vastly superior cutting ability. Dotanuki's smiths didn't care much for aesthetics; instead, they focused on strength, cutting ability, and durability in the field. They were renowned for producing blades that could withstand the harshest conditions, the most difficult battle conditions, and survive to return to combat day after day, year after year. It is known that Nobunaga himself had a Dotanuki reserved as a battle sword. There are records that mercenary clans, especially the two most powerful Shinobi (historical ninja) clans, Iga and Kōga, acquired these blades from the Muromachi period, until the massacre and extermination of the Iga clan in 1581. The Kōga, on the other hand, they continued to be used in the service of Nobunaga's Shogunate, at least until the Shimabara rebellion in 1637, which is the last historical record of Kōga troops participating in the war.

The polishing is not recent, it seems to be from years ago but it is quite well preserved, some light signs of use and other ones but really not important, no fatal damages. Preserve a razor edged. A new polish does not seem necessary.
