Japanese sword question

[Kubur]

Hi Guys,

A friend asked me some information's about a Japanese sword.
But it's far - far East - from my expertise.
Could you help him?
Is anyone good enough to translate the inscription?
Thank you

Hola,Kubur,
After putting the words(盛常) on YahooJapan and searched it,I believe it is the name of the bladesmith,since that indeed is a common(?)name of Japaneses.
I am affraid of that is all information I have though.Have very little interest into Japanese weapons and not able to read Japanese.
Wish your friend get better help&information.

You will also need to turn the pictures upside down as kanji are read with the blde uppermost and the nakago(hilt) at the bottom

Mori Tsune = vain

signature forgery is also a great japanese art form.

from the index of japanese swordsmiths:

Thank you all
As i said I unstand nothing about these swords.
I'm not on the forums mentionned because it's not really my interest...
If I understand Mori tsune Japanse blades are like Assadallah Persian blades???
Copies of copies to keep a prestigious name???
