Inspired by the WWII Trench knives, the Boomknives are a pair of brass-knuckles, each containing a short, sharp dagger, perfect for close-quarters combat.
Just like Blue Shark, they have a built-in pressurized ejector for the blades, allowing them to be ejected out and fired at somebody via squeezing the knuckles hard enough. This TNT-based system is specially effective against armored targets. If the blades manage to pierce any surface, they will explode shortly after into a violent concussion shockwave. The blades are then instantly rebuilt.
Just like the Aeroblade, Boomknives can be overcharged, which enables the user to perform high-velocity slashing.
It is one of the few weapons that can be used in pairs.
