White Light Chakra Sabre

The White Light Chakra Sabre was a tantō that originally belonged to Sakumo, 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, and the blade was destroyed but reforged after. Once an adult, Kakashi did any more use.

In the movie Naruto Shippūden 3: Inheritors of the Will of Fire, when Hiruko met Kakashi at the end of the war, it see that the White Light Chakra Sabre was reforged.
