The Raigekijin (雷撃刃, "Lightning Blade"), also known as the Thunder Pike, was a spear used by Hiten, the eldest of the feared yōkai duo, the Thunder Brothers. It was capable of discharging large amounts of electrical energy. It was broken in half during Hiten's battle with the hanyō Inuyasha and later collected by the last-surviving member of the Thunder Demon Tribe, Sōten. It was hung on a wall of the Castle of the Thunder Brothers.
