For anyone living in this time, it is quite unfathomable to think about direct combat. Usually, when we think about self defense weapons or weapons in general, they are mostly technical. Since the advent of guns, it’s become less likely that people will use anything else. But there are some classic weapons that work quite well despite being simple and seemingly harmless. Brass knuckles are one of these weapons that have stood the test of time in many ways. They were invented centuries ago and are still in use because they are built to last and cause pain. With so much technology, knuckles might seem really ineffective but they are not. You can actually use brass knuckles for confronting a host of different life-threatening issues.
