White Light Chakra Sabre

The White Light Chakra Sabre was a tantō that originally belonged to Sakumo Hatake, but then he 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 "Konoha's White Fang". This blade was destroyed during the Third Shinobi World War when Kakashi used it to fight Kakkō.

Trivia

 * In Naruto Shippūden 3: Inheritors of the Will of Fire, when Hiruko met Kakashi at the end of the war, Kakashi is seen with the White Light Chakra Sabre, despite it having been destroyed already.
