Zao's sword is a unique Chinese officer sword in Fallout 4.


This section is transcluded from Sword. To change it, please edit the transcluded page.

These swords are made in the style of 7th century jian double-edged straight swords. Produced by the People's Liberation Army specifically for use by its officers and issued in the Sino-American War, many were captured and came to the American home front as souvenirs; some even found their way into fifth columnist hands. Since the Great War, these weapons have become an uncommonly used weapon by wastelanders and raiders alike.

This particular blade belonged to Zao, the captain of the Yangtze submarine.


Despite being a unique weapon, Zao's sword lacks any legendary effects, making it identical to a normal Chinese officers sword in all regards.
