This dagger is the core weapon of the "Rotor Blades" mechanized infantry unit, forged from a high-hardness chrome-vanadium steel alloy. Its sharp, double-edged blade with a spiral-textured handle is optimized for piercing through armored vehicle plating— the blade’s tapered tip concentrates kinetic force, while the spiral grip ensures maximum control during high-force thrusts.

The star-shaped hilt prevents hand slippage when wearing heavy gloves, and the hexagonal pommel can be used as a wrench for adjusting mechanical equipment. However, the steel alloy is prone to corrosion in saline environments; soldiers must coat it with anti-rust oil before amphibious missions.
