The blade has been shortened and should be around 500 years old. The smith's name is hardly visible and 3 characters....last one likes like "Sada" and its for the experts to make out.
The tsuka has a family Mon indicating that the owner came from a samurai background. Furthermore, this beautiful blade has many nicks on its cutting edge that I polished off but the battle scars, I am leaving them as an honor of it been used in actual battle.
Overall, a very heavy and healthy blade.
