A weapon consisting of heavy brass (the cheap plastic ebay ones dont count) that have holes for you to put your fingers through, in order to get a grip and form a fist. Once this is done, you can use the weight and hardness of the brass to injure soft flesh. Pretty effective at ruining people's day, but if you dont know how to fight you may get it taken off your own hands and then used against you. Imagine that.

A weapon in which are shaped into a knuckle that allows you to place 4 fingers into it's holes. Made entirely of brass and are to improve the power of a punch. Often a rolling punch is required. And correct finger hold to avoid finger breakage or injury to fingers might be needed.

First seen the most of was in the world war (but co existed before that and the original creator to this day hides only behind thoeries). Brass knuckles were first welded on to a combat / assassin knife handle. Later on it became it's own seperate individual piece of weapon without a knife, so it's said.

They have been used over the last century for hand to hand combat in the war, for defense and attack, to torture (as some come with spikes and studs that date back to the early 20s). And in to this day and age used by gang members, and other troubled individuals. Or often used for self defense by certain people who think that's something smart to do.

Real brass knuckles aren't the kind you see lying around today that are made of alloy and other cheap metals, often referred to as "second rate metal knuckles", but real brass knuckles are made of solid brass and weigh anywhere from 10 oz and up and are harder to find and get now a day's and have a price tag to usually match that.

Real brass knuckles have costed lives with one hit. Brass knuckles are highly against the law usually resulting in a class a or b misdemeanor, which means 6 months to a year in county jail if just caught with them, plus a fine. But it depends on the enforcer. Few get off with warning's. If you strike somebody with brass knuckles or intend to, it is assault with a deadly weapon, or attempted murder, both felonies.

Brass knuckles have proven to be highly deadly weapons if in the wrong hands as some come in a variety of shapes and sizes and are usually as painfull as they look to get struck by one. They may break or shatter bones. Though often second rate metal knuckles are generally less powerful than there brass predocessor unless they are heavy (7.0 oz or more) and / or big (fat boy knuckles), needless to say.

Extreme sharp spiked knuckles second rate or not may cause a brutal bodily injury leaving somebody without much of a face if used repatively by the attacker.

Brass knuckles are often referred to as paper weights now a day's to avoid legal issues.

Second rate knuckles can be found in your nearest self defense online store.

Very hard plastic knuckles with bumpers can also bring a punch but are less so affective than there metal predocessors, needless to say. They to are also illegal in most places now a day's. They too can injure your fingers.

Carrying brass knuckles is a bad idea, an alternative to keeping a gun at home may be brass knuckles however, or SAP gloves, which are gloves that law enforcers use for there larger or drugged out suspects. They have metal BBs sewed and weaved into the knuckles and are made of punishing leather and are often more concealable than brass knuckles. They to can bust open faces.

There is also bottle opener knuckles, which can open bottles forreals hence the name, and require two fingers instead of 4 and are half the weight and size of regular metal knuckle, I have yet to see these in brass. They have "teeth" at the top of the knuckle. And can be fairly labeled as "compact jaw breakers".
"Check it out man, I got some brass knuckles!" 'Man first of all those are Not real brass knuckles there second rate knuckles, second of all your stupid because if you get caught you'll be in big trouble over some stupid piece of metal, third of all your a wussy that can't use your hands because anybody can pick up and use a weapon for a typical fight. Brass knuckles dont make you look like a bad ass they make you look like a fuckin loser.'

Also called knucks, or knuckle dusters. They are pieces of steel made to fit around the knuckles. These are very deadly. A punch can fracture bones. A Punch to the head may kill. However, you shoudn't punch straight with brass knuckles like most people do. This will hurt your fingers. You should swing at them instead. These things are very infamous, and are effective at what they do best, ruining people. Therefore, if you are caught with knuckles, you go to jail.

Brass Knuckles are one of the most effective melee weapons ever made. They can end fights in 1 punch. Theres other types of knuckles, like Spiked Ones, which are very dangerous, and shatter bone, AND tear skin. Theres also a trench knife, which is commonly used in the US in WW2. Trench knives are short knives with brass knuckles as handles.
Sal and Bob got into a fight, and Sal was beating the crap out of him, so Bob pulled out his knucks and shattered Sal's arm in one blow. Brass knuckles are the last things to expect from a "fair fight".

The most hardcore weapon around today! You wear them over your knuckles not only to protect them, but to SERIOUSLY fuck your opponent up!

Warning: There is a differrence between regular fighting and extreme brute-force fighting. Brass knuckles should ONLY be used in extreme brute-force fighting!
