The statement this sword makes: You want the power of a lightsaber, in the form that looks like a space-age keychain toy. When you wield this weapon, the universe seems to align in your favor--by calculating the trajectory of every particle in existence, it's almost as if you can predict the future. Trippy.
Should you wield it in a fight? Setting aside the whole precognizance, future-sight thing, the Monado probably shouldn't be your first pick for a swordfight. "The thicker the blade, the more material it has to push out of the way as it enters into the target," says Clements. "So if you have a blade that's very thick, it has to have a curvature and a really hard edge in order to slash." And that giant ring in the blade wouldn't serve much of a purpose, besides giving your opponent something to grab onto and wrench the weapon from your hands. "This would be something you could slice with," concludes Clements, "but it's impractical because there are far more maneuverable and agile designs, that don't have the deficiencies [that come with] a big hole."
