I got this sword at the Facts convention in Belgium, and suspect it's from an
anime, but I am not sure which one. Is there anyone who knows it?




That should be [Uchiha Sasuke](http://naruto.wikia.com/wiki/Sasuke_Uchiha)'s
[Sword of
Kusanagi](http://naruto.wikia.com/wiki/Sword_of_Kusanagi_%28Sasuke_Uchiha%29),
from the [Naruto series](http://naruto.wikia.com/wiki/Naruto_%28series%29):

However, I'm not sure whether or not [the Uchiha
crest](http://naruto.wikia.com/wiki/Uchiha_Clan) is ever shown to be on the
hilt of the sword in the series.
