A small knife with a straight blade, designed and balanced so it can be thrown with ease. Can be used to silently take down enemies at range, or used as a melee weapon if required. It can be purchased from some less-than-reputable sellers, or save a trip by recollecting the knife after throwing.
This projectile is provided during the mission "Paying a Social Call", and can be purchased from a Fence or the Trapper after completion. Alternatively it can be obtained earlier at Six Point Cabin before the mission "Paying a Social Call" where the hideout would not be occupied yet.
The Improved Throwing Knife can be crafted at a campfire with an existing throwing knife and rare bird feathers, while the Poison Throwing Knife, also craftable at a campfire, can be crafted with an existing throwing knife and Oleander Sage.
Several ranks of the Weapons Expert Challenges require the use of throwing knives.
