👉 An effective weapon in combat or self-defense is one that offers a significant advantage over the opponent in terms of stopping an attack, incapacitating the attacker, or neutralizing a threat. It typically possesses characteristics such as high accuracy, reliability, and the ability to deliver lethal force with minimal effort. A well-chosen effective weapon should also be familiar, allowing the user to react instinctively and efficiently, while being balanced in weight and design for ease of handling. Examples include a well-calibrated pistol, a high-quality knife, or a specialized hunting weapon like a bow and arrow, depending on the context and user's needs.
