What does knuckleduster mean?
A knuckleduster is a weapon worn over the knuckles to make a punch more painful or damaging. Such devices are typically made of metal and may have projecting ridges or spikes, although the term is also used for brass knuckles more generally. The word most often appears in legal reporting, criminal investigations, and discussions of weapons offenses, where it conveys a distinctly violent connotation. In British usage, “knuckleduster” can especially suggest a spiked metal implement, while American usage commonly applies the term to brass knuckles and similar hand weapons. It should not be confused with a protective knuckle guard worn for sports or manual work: a knuckleduster is intended to inflict harm, whereas a guard protects the wearer from injury.

Etymology of knuckleduster
“Knuckleduster” is a compound formed from “knuckle” and “duster,” the latter meaning a covering or protective piece. The compound developed in the 19th century for a metal covering or weapon fitted to the knuckles. It is related to the same body-part root found in words such as “knucklebone” and, in the distinct sense of a bowler, “knuckler.”
