Wiz: It's true. According to Jetstream Sam, when he and Raiden were fighting, he deduced that every tactic Raiden used was self-taught. And speaking of which, the blade that Raiden carries is known as a High-Frequency Blade. This blade is reinforced by a powerful alternating current and resonates at extremely high frequencies. As such, the High-Frequency Blade can weaken the molecular bonds of anything it cuts, which in term, means that Raiden's blade its capable of cutting through virtually anything.
