A compact, metal weapon designed to fit over three fingers, typically the index, middle, and ring fingers, serves to amplify the force of a punch. This type of close-range self-defense tool increases the density and weight behind a blow, potentially causing significant injury.
Historically, similar devices have been employed in various forms for centuries, often playing a role in hand-to-hand combat. The enhanced striking power afforded by such instruments offers a potential advantage in physical altercations. However, the legality and ethical implications of their use are complex and vary considerably depending on jurisdiction and specific circumstances. Possession, carry, and use may be restricted or outright prohibited.
