A [[sword]] with a blade made of some sort of energy instead of a physical blade. 

The best-known example is the [[Star Wars]] [[lightsaber]], but energy swords are also very common in [[science fiction]] themed anime and manga.

Characters such as [[Kuwabara Kazuma]] from [[Yu Yu Hakusho|Yu Yu Hakusho]] and [[Vegetto]] from [[Dragon Ball Z]] are known for having energy sword attacks.
