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 from moderate to severe damage. 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 18th century, knuckledusters were incorporated into various kinds of pistols such as the Apache revolver used by criminals in France in the late 19th to early 20th centuries. 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. It was advised not to polish brass knuckles as allowing the brass to darken would act as camouflage on the battlefield. 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. 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 cross guard. == Legality and distribution ==
