High-Frequency Blade

The High Frequency Blade (高周波刃, Kōshūhajin) is a powerful bladed weapon developed by the Magic Council.

Description
The high-frequency blade is a sword reinforced by a powerful alternating current and resonates at extremely high frequencies thanks to being superheated from friction induced by the user channeling their magical aura into the Lacrima within the hilt, creating an extremely sharp blade that sears anything that it comes into contact with. The oscillation of the High-Frequency Blade weakens the molecular bonds of anything it cuts, thereby increasing its cutting ability. Striking, cutting, and thrusting attacks are performed with the blade, with the sharpened edge and point used for lethal attacks, and the blunt edge used as a clubbing weapon. Masters of swordsmanship are able to wield the high-frequency blade with accuracy and speed that they are able to deflect bullets. While nowhere near as effective as the magic-charged weapons, the High-Frequency Blade is still capable of piercing through magical armour and defenses, and unlike a magical weapon, it doesn't deplete the user's magic pool. The high-frequency blade folds up like a switchblade for storage; also, a high-frequency blade is usually treated with anti-magic coating as they are often used to block magic-based attacks.

Trivia

 * The High-Frequency Blade was inspired by the weapon of the same name from Metal Gear Rising, albeit tuned to the world of Fairy Tail.
