Got my knucks promptly and discretely, I was very pleased with the service. As for the knucks themselves, I'm actually hoping I never have to use them, cause these things are DEADLY. The knucks are about 6 ounces and 3/8 wide, and feel hefty in the hand. I was expecting them to feel lighter, being made of zinc, but they are pleasantly weighty. They fit great in my hand(though it might scuff your pinkie a little were you to actually use them, but that's a minor gripe). The design of the knucks themselves is wicked, these things were made to severely handicap anyone that fights you. The spikes on the knuckles can easily break skin and shatter bone, so a well-placed blow to the face or ribs will instantly drop anyone who gets hit. It also has spikes protruding from the sides, so hammer blows are a deadly option as well. The inside of the holes on mine have some staining from the forging process, so you can tell these were cast at high heat, just like they advertised. I bought these as a self-defense tool for my home(home invasions in my area are tragically common), and I'm confident that, were someone to break into my house, they'd LEAVE my house broken themselves. I recommend this product whole-heartedly, they are a STEAL for the price they're being sold.
