Blade of the East

The  is a unique weapon in Fallout: New Vegas. It is a unique variant of the bumper sword.

Characteristics
The Blade of the East has an effect of -2hp for 10 seconds. It appears that the only cosmetic difference between The Blade of the East and a bumper sword is that it does not have a license plate on the underside of the sword. Legate Lanius can be seen hitting NCR (non-veteran) rangers with it, dismembering and getting one-hit kills. The weapon can also cause your enemies to fly backwards and be knocked out.

Locations
Can be looted from Legate Lanius in the final battle if siding with the NCR, Yes Man, or House. Note that you will only have a limited time to use this, as the game ends soon after the fight. This makes the weapon's appearence fairly useless, as it cannot be used anywhere else in the game.
