Sword

The dao is a low-tech skill weapon in Deus Ex.

Background
The dao is a Chinese broad-bladed sword used by the Triads in melee and as their traditional weapons in Hong Kong, with a more intensive use since the installation of a system of acoustic sensors able to detect gunfire by 2052.

In China, the dao is known as one of the four major weapons, referred to as "The General of All Weapons".

Characteristics
It doesn't receive much use because the Dragon's Tooth appears shortly afterwards, and is superior in every way but size. The sword is still useful to break open the lockers, however.
