The White Light Chakra Sabre was a tantō that originally belonged to Sakumo Hatake, but then he passed it on to his son, Kakashi. The tantō gave off a white streak of chakra when it was swung, earning Sakumo his title of "Konoha's White Fang". Kakashi used it to fight Kakkō. However, the blade was destroyed during this battle.
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.
