Blue Shark is a four feett long sword, with an eleven inch grip and one inch hilt as well as finally a three foot blade. It is upgrade of Xero's previous blade, Slicer, although it is slightly lighter.
Xero can detach the blade and throw it at his enemies as a means of attack. After a post after Xero throws the blade, the thrown blade disintegrates into raw energy, flows back into Xero's sword, and his sword regenerates back into its usual self.
