Combat knife (DXIW)

The combat knife is a melee weapon in Deus Ex: Invisible War.

Background
"A heavy military knife. Ultra high carbon steel. Virtually unbreakable. Heft and balance make it suitable for slashing and stabbing."

- Deus Ex: Invisible War description Seems to be similar to the combat knife in the original Deus Ex game.

Characteristics
Very common throughout the game, albeit inflicts low damage.

Unique variant
"Prototype special forces combat knife. Microporous metal releases toxins on contact. Designed for political assassination."

- Deus Ex: Invisible War description The Toxin Blade is essentially a regular combat knife except that it injects toxins into the target every time they are hit with this weapon. The target will then continue to take damage for a shot period of time. The more you attack a target with the toxin blade, the more damage they take from the poison, as the poison is cumulative.

It can be found in an Emerald Suites Apartment in Seattle under a pillow. It inflicts toxin damage along with physical damage.
