Chance's Knife

Chance's knife is a unique weapon in Fallout: New Vegas, and a centerpiece of the graphic novel All Roads. It is a unique variant of the combat knife.

Gameplay
This knife belonged to Chance, one of the Great Khans and a prominent character in the graphic novel All Roads. It has a dark blue grip and the blade is still stained by the blood of the Fiends it last killed at the tribal village. Because it is near Goodsprings, if the player character can survive the nearby cazadores and has a shovel, this weapon can be acquired at a very early level.

Chance's knife qualifies as an improved holdout weapon, meaning that if the player has a Sneak skill of 50 they can carry it into casinos and other restricted areas.

Special attack
It has a special Back Slash attack, which does 70% damage in V.A.T.S. at the cost of 3 fewer action points (requires a Melee skill of 50).

It is possible to execute Back Slash outside of V.A.T.S. (without the required Melee skill of 50 to perform the move) by initiating a power attack (hold attack button) while moving forward.

Durability
Chance's knife can successfully strike about 445 times from full condition before breaking.

Variants

 * Combat knife - the standard variant.
 * Assassin - The Caesar's Legion assassin sent to kill President Kimball carries a special version which is non-playable. This prevents the weapon from normally being shown in inventory, e.g. when pickpocketing the assassin. The weapon is otherwise identical to the standard combat knife.
 * Cass - Rose of Sharon Cassidy carries a special non-playable version of the weapon, also otherwise identical to the standard version.

Location
It's located in Chance's grave, north of Goodsprings, on a hill near the tribal village along with Great Khan Simple Armor. A shovel is needed to access the loot. Once at the tribal village, backtrack towards the main road while looking south. You should see a path leading up the hill and at the top is Chance's grave.

Behind the scenes
In the novel All Roads, Chance used his knife to carve a map of the settlements in the Mojave Wasteland. He also used it to kill multiple Fiends at the tribal village before being fatally wounded.
