The term "sakabato" refers to a fictional sword featured in the popular manga and anime series called "Rurouni Kenshin," created by Nobuhiro Watsuki. The sakabato is a reverse-blade sword wielded by the main character, Himura Kenshin. It has a blunt edge on the traditionally sharp side and a sharp edge on the normally blunt side.

In the world of "Rurouni Kenshin," the sakabato is depicted as a unique weapon specifically designed not to kill. The idea behind the sakabato is that Kenshin, who was once an assassin known as "Battosai the Manslayer," has vowed never to kill again. The sakabato allows him to fight with a sword while minimizing the risk of fatally injuring his opponents.

However, it's important to note that the sakabato is purely a fictional creation and does not exist in reality. While there are historical examples of swords with reversed edges or unusual designs, the specific sakabato from "Rurouni Kenshin" is an imaginative concept devised by the series' creator.
