Well. . . . Aside from being a samurai sword. . . . It is a magical sword which can be used to defeat Aku. . . . But that's about all I know from the series (Wikipedia description). Although by that measure, I'm guessing it has something to do with magic. And by looking on the Samurai Jack wiki, I can see it's pretty close to that, although its power depends on the wielder and can only be used for good.
