Vampire's Edge

Vampire's Edge is a unique Chinese Officer's Sword that does slightly more damage than the regular version. It belongs to Vance (Fallout 3), and can be obtained while doing the Blood Ties quest in Meresti Station. The sword itself is in no way a part of the quest (It is not a reward); you can obtain it before, during or even after the Blood Ties quest. It is located in Vance's bedroom, in the familly cloister locked away inside a 'sword cabinet'. The cabinet looks just like a regular wooden cabinet, except its exclusive name, and it can be unlocked by lockpicking or by using a key. The only way to obtain the key for the 'sword cabinet' aside from using console commands, is to either pickpocket or kill Vance. Vance is rather tough to pickpocket, as even with a Stealth Boy active, you have less than a 50% chance of success. Killing Vance however will make the entire Family hostile towards you, as well as the citizens of Arefu if you have already completed the Blood Ties quest to ally both communities.

When obtained, the sword has roughly 50% intact durability. It can be repaired using ordinary Chinese Officer's Swords.
