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 "Konoha's White Fang" (木ノ葉の白い牙, Konoha no Shiroi Kiba, English TV: White Fang of the Leaf, literally meaning: Tree Leaf's White Fang). 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.
- In Naruto Shippūden the Movie: 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.
