The knuckles are a weapon in Fallout 4.


This section is transcluded from Brass knuckles. To change it, please edit the transcluded page.

Developed in antiquity, this weapon is prevalent in the post-War wastelands.

Brass knuckles, or knuckledusters, take the form of four linked metal rings in a shallow convex formation with a bumper attached to the concave face. The rings are slipped over a combatant's fingers with the bumper pressed into the palm of the hand.

When a punch is thrown, the brass knuckles take the majority of the impact impulse, transferring much of the punch's kinetic energy to the target by way of the harder, smaller impacting surface of the metal knuckles. This drastically increases the likelihood of serious tissue disruption and bone damage.


Metal knuckles designed for increased damage during punching by reducing stress on the attacker's hand. They have a medium swing speed, and punches are delivered in a right-straight punch and a right hook. Only one set of knuckles may be equipped at a time. The ability to pierce armor or add bleeding damage that cannot be mitigated allow this weapon to yield a high damage potential against enemies at lower levels.
