Reliable sources please

Probably Mino, and late Muromachi

There is no shingane on tanto (too small).

There was an umegane ont his sword, It's gone during the polishing (size 1.5mm).

The author of Nihonto Koza is merely giving his opinion. It is said that Morikuni's work resembles that of Kotetsu (with a certain difference in level), yet Kotetsu's work has nothing that can be linked to Osaka,Kotetsu is a pure EDO swordsmith. I will leave you to draw your own conclusions. Question worth 10000: What distinguishes Osaka from Edo?. Morikuni is also quoted in the Shinto Taikan by Iimura (3 blades) and in the Kanzan Sato's Shinto oshigata dictionnary 1 blade.

Hum... Shinto hen page 465

Morikuni is known for being one of the best Edo swordsmiths (shinto era)...

Ichimai boshi = Soshu den and end of Muromachi (sue Seki, sue Bizen etc.). Seen on blade by Horikawa Kuniyasu (Shinto).

They don't know how to write kanji, yet they act like experts. This “Kuni” is engraved in the normal way....

If only the two who downvoted me had any kind of argument, but they don't even have that. Einstein's fans without any doubt...

Learn to look at what you need to look at.... This sword has been suriage, which means that the takanoha yasuri are not the original ones.

OMG

Juyo or simple hozon, the mei must be soshin...
