Pepper spray, stun guns, knives, kubotans and specialized key chains are all effective, non-lethal weapons for self-defense, according to Self Defense Ninja. When choosing a weapon, it is imperative to factor in local laws and regulations, effectiveness and power, ease of use, portability and cost.
As a non-fatal self-defense weapon, pepper spray brings an onslaught of unpleasant affects when it comes in contact with a person's eyes, skin or nasal passages, including temporary blindness, severe irritation, burning, swelling and restricted airways, explains Self Defense Ninja. The active ingredient in pepper spray is oleoresin capsicum, which is also present in hot chili peppers, and the effects can last more than 20 minutes for any target, regardless of size.
Legal to purchase and carry in nearly every state, stun guns use more than one million volts of electricity to shock a person, thereby causing intense pain and involuntary muscle contraction, states Self Defense Ninja. It also emits a loud crackling sound when discharged, likely causing an attacker to reconsider if in pursuit. Stun guns range in size, and can be part of a flashlight that disorients and temporarily blinds a target.
Knives are marketed as fatal or non-fatal, and come in a variety of sizes, notes Self Defense Ninja. They are very powerful and useful for a variety of purposes, not merely self-defense. A knife's effectiveness relies heavily on the training and physical ability of the owner.
