Brass knuckles are illegal in most states. These weapons, also called knuckle dusters, are both defensive and offensive weapons. They interlink with the fingers and protect the knuckles, which helps the person fighting deliver harsh blows to his or her enemies.
These devices were used in both World War I and II, but it's well-recognized today that they are extremely dangerous. They have the potential to break bones and cause life-threatening injuries in some cases.
Some states completely ban the possession and use of brass knuckles. Others only ban metal knuckles. Some states don't make the possession of these illegal unless they're used to commit a crime.
What this means is that you need to be careful if you travel to other states with a set of brass knuckles. Additionally, if you use them against someone, you could be charged with a crime even if you were only fighting in your own defense. The injuries caused by these weapons can be serious, causing cuts, concussions, nose injuries, broken bones and eye injuries.
Typically, injuries from these weapons are not fatal, but there have been cases where individuals have died from the weapon's usage. The hard metal or plastic can easily damage the skin and break bones, so it's no surprise that excessive use could put someone in the hospital or result in death.
If you carry these weapons, even as a fashion statement, it's a good idea to put them away or get rid of them completely. When simply possessing them can get you into trouble with the law, it's a better idea to avoid them. If you are charged for carrying this weapon, your attorney can help you build a case for your defense.
