A small, usually metallic, oval-shaped weapon designed to be worn over a single knuckle, typically made of brass, serves to increase the impact of a punch. This type of impact weapon is often compact enough to be easily concealed.
Historically, such devices have been employed for self-defense or in various combat situations. The added weight and focused force delivery offered by these metallic implements can increase the potential for injury in hand-to-hand altercations. Their compact design and relative ease of concealment contribute to their controversial nature and often lead to legal restrictions on their possession or use. Understanding the potential consequences of using such instruments is crucial for responsible decision-making.
