High-frequency blade, Metal Gear Wiki

A high-frequency blade was a sword reinforced by a powerful alternating current and resonating at extremely high vibration frequencies. This oscillation weakened the molecular bonds of anything it cuts, thereby increasing its cutting ability. Striking, cutting, and thrusting attacks were performed with the blade, with the sharpened edge and point used for lethal attacks, and the blunt edge used as a clubbing weapon. Proficient users were also able to wield the blade with such accuracy and speed
