chosen: user
chosen: To use a brass knuckle, grasp the knuckle in your hands so the brass shield is positioned facing away from you. Next, make a fist and cover the shield with your forearm. When you punch, the shield will cause greater force to be transmitted to the impact area, resulting in a more powerful strike.
