Lightweiht, flat and suprisingly higly efective knuckle-duster, upcycled from old seat belt buckle. Very secure and comfortable grip. Really efective punch even with small power.
It’s pretty cool self defense tool. This one is better for man hand. Easy to carry in your pocket, inner side of your belt etc.
One piece only.
