Unknown katana mei


Can anybody translate this kanji I found on a katana I recently bought?

「八龍刀」  
A sword probably made in China.  
The name means literally _eight dragons sword_.

[Here](http://sekaitouken.blog.fc2.com/blog-entry-73.html) is another 八龍刀.

A famous Japanese old legendary talk of **Yamata no Orochi** or _8-branched
giant snake_ is right [here](https://en.wikipedia.org/wiki/Yamata_no_Orochi),
and in this article there is [a photograph of a
sculpture](https://ja.wikipedia.org/wiki/%E3%83%A4%E3%83%9E%E3%82%BF%E3%83%8E%E3%82%AA%E3%83%AD%E3%83%81#/media/File:Sakaiminato_Mizuki_Shigeru_Road_Yamata_no_Orochi_Statue_1.jpg)
of seemingly eight dragons, not eight giant snakes, but the legendary talk
probably has nothing to do with the 八龍刀 _eight dragons sword_ which is shown
by the questioner.
