A self-defense force multiplier is an attribute that dramatically increases the effectiveness of a technique or weapon. Force multipliers are often justified when a disparity of force exists. Disparity of force is defined as a situation that any reasonable person would conclude places you at an overwhelming disadvantage in your effort to protect yourself against immediate and serious bodily injury. Understanding force multipliers and when to use them will help you prevail when the odds are against you.
