Brass Knuckle (5e Equipment)
From D&D Wiki
Simple Melee Weapons
Brass knuckles, or knuckledusters, are pieces of metal shaped to fit around the knuckles. Designed to preserve and concentrate a punch's force by directing it toward a harder and smaller contact area, they result in increased tissue disruption, including an increased likelihood of fracturing the victim's bones on impact. The extended and rounded palm grip also spreads across the attacker's palm the counter-force that would otherwise be absorbed primarily by the attacker's fingers, reducing the likelihood of damage to the attacker's fingers.
Variant. A knuckleduster deals damage equal to your unarmed damage + 1. This is normally 2 bludgeoning damage. Care should be taken if you allow this variant with monks as it will ultimately deal more damage than other monk weapons.
