Wakizashi with very interesting provenance - seeking translation

[dsp]

Hello, this sword is not for sale and any information provided will not be used for commercial purposes. 

 

I am seeking translation on this sword which I previously posted on Nihonto board.  See post on that board for more details.

 

One member on the Nihonto board translated the name as Echizen Yasutsugu.

 

If anyone is able to offer more complete translation.  It will be greatly appreciated.

Echizen Yasutsugu is correct for the left picture.

 

On the right is 

以南蠻鉄於武州江戸

Motte nanban tetsu oite Bushū Edo

means: made with southern barbarian (aka foreign) steel in Edo of Bushū 

 

This is a very common inscription on Yasutsugu swords. There should be a good deal of info available in English if you search on that phrase. 

The way the "tsugu" character (継) is inscribed is unusual. May be an idiosyncrasy of one of the Yasutsugu smiths, but I couldn't find anything online. Of course, there is always the possibility that it is a forgery as well.
