This replica sword is modeled after the anime and manga series Naruto:Shippuden. The manga portrays Sasuke's sword as white in color whereas in the anime, its black.
In the series, this sword is wielded by Sasuke Uchiha, the sole surviving member of the Uchiha Clan.
Sasuke can expand on his sword's might by channeling his lighting charkra into the blade with chakra flow (Chidori), which will increase its sharpness greatly through high frequency vibrations, as well as increasing its cutting range. This would allow Sasuke to cut through almost anything, as well as numb the target who has been pierced by this lightning blade.
This sword is an anime replica and is intended for display only.
