It's a hard concept for decent people to get around, but for a career criminal they spend the majority of their time devoted to their career...just like you do. A rapist, a serial killer, a spree shooter, general thug doesn't think about getting on with a normal like. Rather they attempt to appear normal so they can operate in the same theater as you and I. Hence the old saying a wolf in sheep's clothing.
Here is the last thing I want you to remember as we go about breaking down the target areas of the body. Think about it now, occasionally as you read this by stopping and closing your eyes, and when you lay in bed....IT-IS-GOING-TO-BE-A-CLOSE-FIGHT.
Worried a bit? Hesitant with that idea? Scared out of your head but don't want to really admit it...that's cool get it out. Now take a minute to close your eyes, wrap your weak hand around his throat, take that thumb of yours and *click* open that tactical folder of yours and win.
Upfront. Stabbing beats slashing for the purposes of increasing a lethal wound quicker. A slash bears a strong psychological bomb. Lance the body and it opens. When it opens things spill out. It also creates a long external but, shallow (relative to how deep you cut) wound area. Blood and muscle are now exposed and there is likely nerve damage but the slash cut does its best on bare skin. Great if your attacker is naked or even half naked. Not so good if he is wearing a down jacket. Though from a tactical advantage the slash-cut to the face (especially above the eyes) is going to be a thin cut because of the amount of bone-to-skin but head wounds bleed bad. Blood in your attacker's eyes is going to keep blinding him until he contends with it. This requires putting pressure on the wound, which in turns requires one or both hands. Thus increasing your target area on him and decreasing his ability to cover his vitals.
Queasy uneasy yet?
The vulnerable areas of the head are the face and the base of the skull, which if you look at sits higher than you think. The chin for example can sit more than a few inches below the skulls base by comparison.
So while stabbing and slashing the back of the skull is pointless when compared to other parts of the anatomy, the skull's base is not a bad area to attack. Get below the Occipital region and target the Cervical Vertebrae with stabbing blows or deep cuts and it's light out. Sever the spinal cord here and death is anywhere from tenths-of-seconds to-seconds.
How would that be possible?
Get in the habit of mentally visualizing an attacker inside of an elevator and launching an quick barrage attack upon you. Or trying to shove you into the back of a van. Oh I get it. You are thinking this part is for the women...cause you know...rapists. True enough. But at some point Bob Levinson, Daniel Pearl, Paul Chandler and only a few other hundred thousand men through out history have been forced into captivity. This isn't a “please come with us kind of thing” it's an shit kicking assault until submission happens kind of thing...and that is just the kidnapping.
The Virginia Tech Massacre, where guns weren't allowed on campus, could have ended in short order if someone with balls and a blade would have chin grabbed the son of bitch and cut his throat.
And then there are others who don't fight because they can't think beyond the pistol. If this is you I suggest you stop and reorganize. Because there may come that day where you are vacationing somewhere where your conceal carry permit is broken and as you look out over a beautiful chasm from a suspension bridge taking in the view with your family the guy next to you decides he want to throw people off it...just because.
The end game is this. There is a difference between "feeling safe" and having viable options to safely defend oneself.
