Brass Knuckles - History and Variations

History and Variations

Metal ring and knuckle style weapons date back to ancient times and have been used all over the world for many hundreds of years. Cast iron, brass, lead, and wood knuckles were made in the United States during the American Civil War (1861–1865). Soldiers would often buy cast iron or brass knuckles. If they could not buy them, they would carve their own from wood, or cast them at camp by melting lead bullets and using a mold in the dirt.

Some brass knuckles have rounded rings, which increase the impact of blows. Other instruments (not generally considered to be "brass knuckles" or "metal knuckles" per se) may have spikes, sharp points and cutting edges. These devices come in many variations and are called by a variety of names, including "knuckle knives."

By the late 19th century, knuckledusters were incorporated into various kinds of pistols like the Apache revolvers used by criminals in France in the late 19th century to early 20th century. During World War I the US Army issued two different knuckle knives, the US model 1917 and US model 1918 Mark I trench knives. Knuckles and knuckle knives were also being made in England at the time and purchased privately by British soldiers. By World War II, knuckles and knuckle knives were quite popular with both American and British soldiers. The Model 1918 trench knives were reissued to American paratroopers. British Commandos even had their very own "Death's Head" knuckle knife, featuring a skull-shaped brass knuckle handle.

A notable knuckle knife still in use is the Cuchillo de Paracaidista, issued to Argentinian paratroopers. Current-issue models have an emergency blade in the crossguard.
