I've been doing Kenjutsu for a few years now and I've done a good bit of reading in terms of strategy...
In regards to defending the self, the only real way to get out of a fight/flight situation is to not get one in the first place. Walking with friends, avoiding shady parts of town, being concious of your own surroundings.
In terms of weaponry, the best weapon is the one that you have on you. You could maybe "make your body a weapon", but I do think that's a bit cliché.
So a dude ambushes you and wants to take advantage of you and pulls a knife on your throat, what can you do? In the movies you'd probably kick him in the nuts and he'd miraculously drop his knife and you make a run for it. Maybe in reality you've tried that, but he's got you in such a hold and you're so weak that you have no option but to succumb to his demands.
Did you know that a knife is more likely to kill you than a bullet?
What are your options?
- Carry some sort of weapon
- dedicate yourself to some form of non competitive martial art
In terms of carrying some sort of weapon,
There are lots of different weapons for use in self defence.
- Blunt weaponry such as a telescopic baton has a great intimidation factor and can be paired with classic jujitsu techniques to help you take down any attacker. This weapon does need training though, and don't expect that just by carrying it you'll be able to take someone down.
- Knives can be great if you know how to use one and practice quickly gaining access to it. If used properly, it can compliment any martial arts style and there are even a few martial arts styles based around knives. Something like a push dagger can be easily concealed and are relatively easy to use.
- Guns are great, but using one requires a lot of discipline, observation of laws and need a lot of training. Anyone can pull the trigger, but using a gun properly is an art in itself.
- Non-lethal guns are a good available option for where lethal firearms are not available. There's a pepper-gel gun called the guardian angel that can easily incapacitate an assailant with ease and is compact enough to be concealed.
Things to remember with using any weapon:
- Not being trained to use the weapon can be detrimental. You need to know everything about how it works and everything about how to use it.
- A weapon can just as easily be turned against you.
- Escalation of violence could lead to a gun being pulled on you.
In terms of martial arts, there are quite a few good ones, though a few things to avoid.
- If you're thinking of looking up one for self defence, I would personally avoid something like Karate or Judo as their modern focus is more on competition and sport. You will learn virtually no weapon defence in these martial arts which could be crucial.
- Ones I would recommend are Aikijutsu, Aikido, Jujutsu (not to be confused with the Brazilian variant), or any martial art that has a focus on grappling and incapacitating an attacker. The three mentioned aren't necessarily sports and have a focus on taking down an armed attacker while you yourself are unarmed. Jujutsu also has a bonus of doing baton training and literally being about taking down an opponent with their own strength.
Some things to remember
- Just because you do martial arts in a safe environment doesn't mean you're able to perform it in a stressful situation.
- You should never assume that an attacker doesn't have any knowledge of any martial art.
- Thugs and Gangsters literally go home and practice how to stab things quickly and not get stabbed.
In summary, fighting and getting out of a situation is best to be avoided at all times, even if you think you can take them on. If you get into a situation, then try to keep self preservation a priority. If you want to get something to help in case you end up in a situation, learn how to use it properly or you'll end up with it being used against you.
I hope my advice helps. Fighting is universal and there's no such thing as the strongest person being the winner.
One of the below quotes is by Musashi Miyamoto who, interestingly much like C2, said that there are only a few moves you ever need to know to take down an opponent. Going to look into C2 for a bit.
