Throwing Knives are a thrown projectile weapon used by the Infiltrator in Tribes: Ascend. They have high accuracy and "laser-edges". Hi-Rez release video, below. This weapon can be unlocked for 420 Gold or 75000 XP.
"Throwing knives deal impressive damage on a direct hit, and have a small splash damage radius as well." In-Game Description.
The knives offer good damage per hit and travel in a straight line when fired (note that they are not affected by inheritance). They also have a tiny area of effect on miss that deals 100 damage, and serve as a slightly more challenging replacement for the SN7 Silenced Pistol. These also offer a better alternative of taking down Light Turrets and EXR Turrets, as you can down one with a knife followed with a Melee..
- Advantages: Higher damage per hit, better accuracy.
- Disadvantages: Smaller clip, slower projectiles.
Since neither the silenced pistol nor the throwing knives are hitscan and the knives do more damage, it is worth it to learn to aim the knives if you have unlocked them already. However, for the price they can be considered unnecessary by anyone looking to be economical with their XP.
