If you are a Naruto fan, you would definitely want to have an actual Sasuke sword. This katana called "Sword of Kusanagi" was what Sasuke carried throughout the entirety of Part II. It was repeatedly proven to be very durable.
But it was clearly not lava proof. :(
Sasuke sword looks like this:
Cool, isn't it?
It's good to have it for the purpose of Naruto cosplay.
By the way, do you know what "The Kusangai" refers to in Japan?
It is one of three sacred treasures of ancient Japan that represents valor in Japanese history.
This is the perfect katana for Sasuke considering the fact that he has great courage against any enemy.
