Throwing knives

Throwing knives are a low-tech skill weapon in Deus Ex.

Characteristics
Throwing knives are silent and inflict relatively high damage, sufficient to kill a common trooper in a single headshot at the untrained skill level. However, their effectiveness is limited by their low range and accuracy. The accurate range of throwing knives is 40 feet. Thus, the trajectory of a thrown knife is straight up to 40 feet. After traveling 40 feet, the thrown knife will begin its downward descent due to gravity.

Unlike conventional weapons, the accuracy of throwing knives cannot be increased by weapon modifications. Accuracy can only be increased by weapon skill and the Targeting augmentation. The maximum accuracy that is obtainable is 90%, from a combination of master weapon skill and Tech 4 Targeting.

Throwing knives are internally classified as hand-to-hand weapons; thus, they receive bonus damage from the Combat Strength augmentation. A combination of master low-tech skill, Tech 4 Combat Strength, and Tech 4 Targeting yields a modified damage of 51, enough to damage and destroy turrets, camera, and alarm panels.

Trivia

 * The weapon's internal name includes the word "shuriken." Beta images and design document v13.12 indicate that throwing knives were originally shuriken at one point during the game's development.
 * In design document v13.12, the shuriken is given the following description: "Favored weapon among HK fighters. In the future, shuriken are made of non-metallic carbon-fiber and are virtually undetectable."
