"Sakabato" is a term used to refer to a reverse blade sword, like the one used by Kenshin Himura in the series "Rurouni Kenshin." However, it's important to note that sakabato, specifically referring to a sword with a reversed or inward-facing blade, is a fictional concept.

In reality, traditional Japanese swords, such as the katana, have a single-edged, curved blade with the cutting edge on the outer side. This design allows for effective cutting and slashing techniques. Reversing the blade of a traditional sword would render it ineffective for its intended purpose.

The idea of a sakabato was created for the story of "Rurouni Kenshin" to symbolize Kenshin's commitment to non-lethal combat and his desire to atone for his past actions. It is a fictional concept and does not exist as a functional weapon in real life.

While there are modern versions of swords with blunt or unsharpened edges, intended for training, cosplay, or decorative purposes, these are not true sakabato in the sense of having a reversed blade. They are designed to be safe for use in training or display, but they do not have the functional characteristics of a true sakabato as portrayed in the series.
