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 or at Ewing Basin.
Additionally, they can be found from looted Murfree Brood members.
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.
