White Light Chakra Sabre

The White Light Chakra Sabre was a tantō that originally belonged to Sakumo Hatake, who passed it on to his son, Kakashi. It was a straight-bladed tantō with a small, circular hand-guard. It gave off a white streak of chakra when it was swung, thus earning Sakumo his title of. This blade was destroyed during the Third Shinobi World War during Kakashi's fight with Kakkō. In the anime, it was later shown repaired with Kakashi still using it for missions.

Trivia

 * In Naruto Shippūden 3: Inheritors of the Will of Fire, during the flashback right after the Battle of Kannabi Bridge, Kakashi is seen with the White Light Chakra Sabre sheathed, despite the blade having been destroyed at the time.
