Seriously though, not everyone is suited to finding weapons or being able to fight with years of practiced technique. In fact the majority of people have no experience in those areas, and even if you do sometimes they won't always come in handy. You may black out and wake up tied up in someone's basement and in times like that it's easy to lose your cool.
But just remember, never panic, and never be caught off guard.
As someone who is a tad on the tinier size, it's easy to find yourself in a situation where you have the bottom hand. Still though that doesn't mean you can't cheat. Here's a quick list of scenarios.
Pinned to the ground? Easy. First of all, don't get pinned. If someone's trying to pin you, they're probably coming at you from the front or back. Bend your legs and turn into the blow and hit them right in the center of their balance. Knock them over and then bring your foot down on their neck. Easy kill. If you screw up and get pinned anyway, there are still a couple of things you can do. If they have you on your stomach with your hands behind your back, get a feel for where they're holding your hands and pull towards their thumbs, if you do it fast enough your hand will slip out of their grip. Bring them to the ground and push off to the side as opposed to straight up, you'll knock them off of you and you may get a good kick to the face while you are at it. If they have you on your back, get your hands free the same way, make a v with two of your fingers and get the fucker in the eyes. If they happen to have a knife at your neck, may I redirect you to my first bit about DON'T GET PINNED.
Tied up in a chair? Well hopefully you kept something sharp on you in a place you can get to it, like a key necklace or a bracelet with a razor. If you failed to do that, relax and concentrate on breathing. If you expand your chest enough you can loosen the ropes and slip out. Same goes for your hands. Pull on the ropes until they loosen up enough for you to get free.
Got a bastard choking you from behind? Bend your knees, lean forward, and flip the guy over. You have to do it fast though or you'll get caught under them. Once you've got him on his back, bring your foot down on his neck.
Got a bastard choking you from the front? Fall on your back, and bring your legs up in-between you and kick at the abdomen. If it's a guy, get him in the balls. Bring your hands behind you so you can pop right up again.
In a headlock? Push the guy away from the side, or kick his feet out from under him. Whatever works.
Got a guy with a gun aimed at your head? Bring your hand up behind you in his blindspot and bat the gun away in one swift and quick move before they guy realizes what you've done, as soon as the gun isn't pointed at you bring your other hand over and shove the guy onto their back.
Vital areas to go for are the nose, the temples, the philtrum, the testicles, the neck, the adam's apple, the base of the spine, the heart, the back of the skull, the abdomen, the ankles, the eyes, and the waist.
To knock someone off balance aim for their center (right under their ribcage but above their crotch, if you kick them in the ass from behind they'll fall over too,) or their ankles.
To snap someone's neck from the back, place one hand over their mouth, the other on the back of their head and jerk abruptly to the side.
To snap someone's neck from the front, place both hands on the side of their head. Your thumbs should be gripping them from behind the ears. Wrench their head towards your dominant hand, and pull up.
Bring the palm of your hand up under someone's nose and you can shove it back into their brain.
Also if you punch someone hard enough in the ribs on the left side there's a very good chance you can send a bone into their heart.
Gouging out the eyes with your fingers or another sharp object is good too. You can't be squeamish ladies and gentlemen.
Here's a list of some easy to find and inconspicuous weapons to keep on hand.
-Hairspray (Works extra nice if you have a lighter.)
-Pen or a Pencil (Shove it in the ear or the eyes)
I'm wary of using things like shovels or baseball bats because they leave an opening that's very easy to push through. Just keep them close to your body, and hold them over your head when you swing as opposed to swinging them back.
Practice throwing items like the hammer or the knives. I happen to have a dart board I practice on. Practice until you can get the target 20/20 times. I also suggest researching some more of this stuff on the internet and trying it out for yourself. Practice makes perfect.
The best thing is to just always be prepared. The less prepared you are the easier it is to find yourself in a bad situation. So keep calm, remember your technique, and give em hell.
