Monofilament Wires

The  are weapons used by Walter C. Dornez.

Properties
Walter's are ultra-sharp and super-thin, so much so that they can hardly be seen by the naked eye. Even Vampires like Jan Valentine failed to see them, despite his senses being enhanced, until it was too late, allowing Walter to painfully yank the ring off of his lip. They are embedded into his gloves and are what he uses as his primary weapon.

Lethality
The wires are extremely deadly, able to cut through almost anything from an entire squadron of ghouls, steel, to entire buildings, with ease. They also appear to be blessed, considering their blue-ish glow and ability to kill vampires. They can also form a type of mesh-like shield strong enough to deflect bullets and can be rigged into a corpse -- even Baskerville -- and use the person as a puppet. It is unknown who first manufactured them, but it was likely Hellsing; he has been seen using them when he was a teenager fighting for in Hellsing: The Dawn.
