Also known as Brass knuckles, knuckle dusters, knuckles (there are different types and this is a broad reference) or Brass Monkeys. Knuckles can be made out of Metal or plastics. Real Brass knuckles can deal an astonishing amount of damage is used correctly. They are harder to find and are very costly. Second rate metal knuckles are the most common and are often called "paper weights" or "belt buckles" to avoid legal issues. Plastic knuckles are the least affective but can be used to get past airport security. Knuckles are illegal in several countries, especially the United States (carrying one in public results in an a or b felony and a large fine. That's jail time of 6 months to one year) They are illegal because knuckles, alongside usually being made of metal, cause deep tissue damage and can brutally tear up someone's face or other area repeatedly struck. They do so much damage because they provide very good support to your fist and in turn, your fist provides a very good punch. You could just as easily do the same damage with a handfull of pencils. The metal does tend to hurt on top of that. Knuckles have been used for years. They have been seen in torture methods, war weapons, gangs, and sometimes self defense. Sometimes they are implemented into the handle of a knife resulting in a Trench Knife. They can also be given spikes, blades, studs or other harmful accessories.
