Name of Weapon: High-Frequency Blade (Or H.F. Blade for short)
Type of Weapon: sword
Appearence: The H.F. blade basicly looks like a regular katana sword, but sometimes, an aura of electricity surrounds the blade. The reason for this is unknown, but it has been speculated that it's extra energy left over from attacks.
History: After he was captured, Raiden got this sword from Solid Snake (Snake got it from the leader of the russian soldiers running around the Big Shell) along with the rest of his gear inside the underbelly of Arsenal Gear. After fending off mass-produced RAYs, Raiden used the H.F. blade during his final battle with the man behind the entire ordeal, Solidus Snake. Raiden has been spotted, armed only with this weapon, fighting new Metal Gear units in an unknown location, but thats the last that was heard of him or this sword.
