It’s not practical and sometimes not even legal to carry a weapon. What is a weapon? A weapon is a specialized tool for projecting force. It serves no other practical purpose than extending force from one body to another. The handgun is a perfect example. Handguns are designed to do one thing - extend force outward, to another human. Yes, a human. Guns and knives are considered deadly weapons. (Note - the EDC Krav Maga Self Defense Keychain is an improvised weapon - more on that later)
When asking what is Krav Maga, people are really wanting to know what is different about the system than everything else. The problem with self-defense techniques is that they are often the starting point in problem solving, rather than the result of correctly applying principles. Krav Maga is advertised as being a principle and drill-driven system, but some instructors and groups do a better job of keeping training in line with advertising than others.
There is a big problem with the subject of violence in self-defense training and self defense techniques. Many instructors start first with self-defense technique, rather than starting with what violence really looks like. The problem is that most people are using the same words - Violence, and Fighting - but are describing different things.
What is the fastest way for a woman to increase her personal safety? Research the best self defence martial art? Learn self defence online? These are good options, but they are not as fast as buying a self-defense gadget. Self-defense gadgets are not usually dedicated weapons, they are improvised weapons.
Seek the truth about your personal safety through data. Stories are exciting, interesting, scary - but stories are different from data - and data is essential for your women's self-defense plan. Stories can include data, but stories are the micro-view. We need the macro-view.
