Due to the weightlessness of chakra and the strong gyroscopic effect generated by it, this sword required a great deal of strength and dexterity to wield, and it was extremely difficult—and dangerous—for the untrained to attempt using. It is three centimeters in diameter and around twenty-five centimeters long. On one side, a metal fixture like a mountaineering carabiner hangs down, the other side is slightly thicker while the center has a black hole. The color of the blade varies, depending on the fact whose chakra has been inserted in it.
