Filament Sword

The Filament sword is a tactical short sword made by the Quantonian Empire, The blade is made of basic titanium with hooks at the tip, The hooks connect a extremely strong and thin filament wire to the hilt of the sword, the wire is the main cutting tool which makes the sword very deadly.
The wire is so thin you would need a microscope to see it, In case the wire breaks the sword still has the secondary titanium blade, this can be used until the sword is taken back to base and repaired, however it is very rare for the wire to break due to how strong it is, so the chances of someone needing to repair it is very rare.
The Filament Sword is one of the most cheapest and deadly melee weapons the Empire has developed. The sword is standard issue and is stored in a specialized sheaf to prevent soldiers harming themselves.
