This two-finger knuckle duster is a perfect accessory to your belt. This buckle is made from 100% pure brass and the rivet for your belt is included. The ovular holes may be something you can slip your fingers through for use as a self-defense weapon, but that is not their intended purpose. You could also unscrew the rivet and have a stylish paper weight! Don’t let the size fool you, this buckle packs a punch! Overall Length: 1.85 inches, Weight: .18 lbs
