The Uchiha Style Kenjutsu (うちは流剣術, Uchiha Ryū Kenjutsu) is a unique style of kenjutsu developed and mastered by Sasuke Uchiha, who passed on the skill to his student Boruto.
This style of kenjutsu utilises moves similar to Japanese iai, where the enemy is slashed at the same moment the user draws their sword from its sheath.
Lightning Release chakra can also be used to coat the blade and increase its sharpness.[1]
