In Reality- using an edged weapon for self-defense

This is going to be the first article in our new column called “In Reality”, in which I will tackle some age old questions when it comes to all things related to preparedness and personal protection. We are first going to start off with the reality of using an edged weapon for self-defense.

We live in a society where you would think that we are desensitized to violence, but for some reason people are still shocked when they are actually witness to it. Even in a state that allows its citizens to carry concealed firearms, the path of someone involved in a clear cut shooting is likely to be a long one. The only thing that would be worse is cutting someone in self-defense.

Here are some obvious hurdles when it comes to the righteous use of a knife for self-defense. On one hand most people do not view knives as a legitimate personal protection tool, even those that are huge proponents of the right to self-defense. When they envision someone protecting themselves with something, it is usually a firearm. Thanks to TV and movies, we have all sat through thousands of shoot, don’t shoot situations. But when it comes to edged weapons, we have seen lots of “knife fighting” with no clear lines drawn as when you would mentally choose to cut as you would to “drop the hammer”. Because of distance and target focus, most on screen blade play is a flurry of body movement that ends with a fatal dramatic stab. The same is true of scenes involving firearms where our good guy appears to be down and out until you see the villain fall backwards. Only then does your mind put two and two together realizing that our hero was able to deploy his gun and fire a contact shot, thus saving his life. A knife is viewed as a sneaky tool that can come out of anywhere.

Keeping the above in mind, let’s look at the physics of using a knife. Being a contact distance weapon that can puncture, tear, or cut flesh, an edged weapon requires that you be able to touch your attacker. At the same time, the attacker must be in a position to employ deadly force on you. This justifies one out of the three things needed that allows you to use deadly force, they have the immediate opportunity.

The next part we need to fulfill is jeopardy, meaning that the attacker is acting in a manner that a reasonable and prudent person would conclude that they intend to kill or cripple you. A particular act in and of itself may not kill you but it would be reasonable to believe that you would as they say in the UFC “not be capable of intelligently defending yourself”. For instance, they are not attacking you with a weapon per se, but you have just been pushed during that altercation and have just had your head bounced off of a brick wall and you are going in and out of consciousness. There is a lot of blood and things are getting foggy, you have weapons on you, once you are out cold will he take your money and run or take your weapons and finish you? The extent of your jeopardy is more like a thermostat that can fluctuate greatly second to second based on multiple factors that if ever understood it will only be weeks, months, or years later. You have to make that decision in the moment with the information you have.

Even though for our purposes we are discussing it last, the first part of justifying deadly force is ability. Let’s cover the five basic examples as they relate to the defensive use of an edged weapon-

Weapon employed against you- if it is a firearm and it is outside arms distance, your ability to do anything even with a knife in hand is very small. Any impact weapon is likely to extend the reach of your attacker, probably negating the use of your knife, even if you have it in hand. Now we are down to knife on knife which makes up a huge portion of cultural martial arts, and “knife fighting”. By definition this would require you to be within reach of someone with a knife and you having pre-deployed yours, or deploying it as you are being attacked. For you to meet this deadly force with deadly force, you would have to articulate that you saw or anticipated your attacker having a knife which provoked you to draw yours. For you to cut them, depending on the blade length, they would have to be in a position to cut you as well. More likely to result in a mutual cutting.

Force in numbers- is a situation where one could articulate that even without seeing any visible weapons, deploying a knife would be more than justified. The problem is tool fixation. When surrounded by a few people, moving forward creates a vacuum where everyone fills in behind you. You can only stab or cut one person at a time. Once the pack moves in and your arm is controlled, the knife is a moot point. I would rather start off with a stick in hand personally.

Able vs Disabled- a situation that is very misunderstood. It does not mean that you walked out of your house with a broken leg and were attacked by someone who was able bodied. It can be as simple as you being knocked down to the ground and you cannot or are not allowed to get up. Not being able to stand up or walk is a disability. Again, another example would be losing consciousness from blunt force trauma to the head or strangulation. This is contact distance fighting where you will need to be able to cut your attacker off of you.

Male vs Female- gender does not change the physics. Even if your attacker is doing something that justifies deadly force, but you are not close enough to touch him, the knife is useless. Again, the likeliest situation is one where you need to cut the attacker off of you.

Physical size and strength- the same realities apply here as they do for male vs female.

In reality, to make the judicious use of edged weapons relevant to the situations where they are most likely to be used, we have to-

* Begin the majority of drills with the attacker initiating contact with the good guy in the form of a punch, push, or bum rush.
* Train the student to use the smallest amount of space and movement necessary to deploy their knife.
* Train the student to use the natural funnels of the body such as the crotch, arm pits, and sides of the neck as landmarks for default targeting, instead of focusing on being at a distance to be able see the body to use intentional targeting.

* The majority of deployment practice should be done from any position other than standing upright.
* A heavy emphasis needs to be placed on the use of open hand combatives that allow the student to create space to deploy the knife, use them along with the knife to include getting the attacker off of them.

Make sure reality is driving your training, not your training driving your reality.

Good thread and I am looking forward to future articles.

In regards to the “Force in Numbers” example, instead of moving forward and being the “pickle in the middle” after the vacuum gets filled, wouldn’t it be better defense/positioning to attack whatever flanking BG is closest to the blade? Then based on the movement/positioning of remaining BGs, again angling to the outside, attack whomever presents themselves? From working to the outside you would only be “fighting” one at a time and create distance and barriers between you and other BGs.

Not trying to be a douche, Im just a fellow martial artist who likes to talk “shop” with other artists

Take care

No worries. I don’t think it really matters. No matter where on the clock you attack first chances are you will be dog piled. Kinda like trying to fight inside of a bag.- George

Another “issue” with peoples perception of the knife, which you alluded to, is the whole idea of a single ending stab.

It has taken considerable time for the firearms training community to concede to the defensive use of constant and unending force until threat has stopped. For too long it was “double tap”. With a knife you must be willing to use repeated aggression, stabbing repeatedly until the threat is gone. It is a hurdle that understandably many people have due to the blurry line people see with stabbing repeatedly. A moral person is often troubled by the idea of carnage that may need to be opened to deploy a knife.
I for one see where it is considerably easier to mentaly forsee and accept yourself shooting being able to safly from a distance with no blood on your hands and likely less on your conscious than having to get you hands dirty doing it “manually”. Of course it is not likely to happen this way.

small rant

Knife fights are bloody & painful, I’d rather use my CCW if needed. I do always carry a knife but it’s used for cutting strings and tape for the most part.

Great article, looking forward to more in this series. I may not always CC (Fed building, school zone, at work, …) but I always have a tactical knife on me. It’s good to explore your options and not get tunnel vision on handguns.

Outstanding as always, my friend.

One thing we focused on was positioning and carrying the edged weapon.
We liked to stress the importance of setting ones-self up for success(ambush) even when compromised. We emphasized making it a point to conceal your true intentions if it is ones decision to carry a sharp tool of some sorts, we also emphasized carrying more than one and keeping at least 2 hidden. We then began from positions of disadvantage where striking was next to impossible and tried to figure out where the most ideal places to carry on the body were.
Of course there was the traditional open carry of a fixed blade over 3" which is a great visual deterrent but does not offer much in the way of suprise or ambush when actually in the “suck”… I look at the open carry fixed blade as a multi purpose tool that has many uses other than making lunch meat out of animal flesh. I am a huge proponent of open carrying a fixed blade whenever feasibly possible. However, I am not a proponent for limiting onesself to just an open carry fixed blade. I like to stress having at least two smaller concealed folders blaced and positions of advantage on the body.

I found that by beginning with being compromised instead a “face off” of some sorts, one can find out where the biggest compromise would be, wether its being tied up our mounted or backed in a corner or what have you.
I found that the most profound compromises was being put on ones back by a larger ferocious opponent and even worse being put on ones stomach and mounted by someone larger and stronger. The stomach is by far the worst place to be put and then to be mounted by a bigger person takes away the ability to target and strike with the body.
I found that an “appendix carried” folder was just the ticket out of a compromise
like that with a fiegned struggle, deployment and repeated thrusts to the leg.
This method of concealed carry works even better when on ones back due to the availability of vital targets.

I also found that carrying in the “small” of the back is ideal for a few compromising postions as is a nech knife and an ankle carried folder. For these I will leave the “why” up to everyones imagination.
I am also a proponent of appendix and “small of the back” carry due to thier low pofile since they enable one to carry with impunity and almost negate being found during a “pat down” all-together.

Good point.

It is arguably the dirtiest and most intimate job other than bludgeoning an animal to non functional bare handed.

I know that our edged tool training has a consistant emphasis on tandem strikes with body weapons along with the blade. Not only does this supersize the trauma but allows you to create the loop holes in the moving and thinking flesh pile that one needs to succeed.
One has to be able to work with thier body first since it isnt as easy as just pouncing an animal and cutting them to ribbons. It isnt as easy as poking and slashing and then taking a kill shot. It IS NOT a duel like most perceive.
I like to look at it like affixing a blade to the bumper of a car and ramming it into flesh. Or, imagine football with knives.
One has to put thier body weight behind the device and smash through the animal since this will create more time and space for you to get the job done.
If you are injuring them you can take your time. You dont have to get sucked into a tunnel. Injuring them gives you time to move back and forth from priority to priority essentially giving all threats equal priority based on thier proximity to you presonal perimeter. Use them against each other, use them against themselves.

George made a good point above regarding default targets like the neck and groin. This is especially important becuase of variable density from animal to animal. A stab or slash to the torso or back or legs will effect everyone differently and some seemingly not at all. Default targets that are equal on all animals regardless of stature is paramount. I dont care whos who, no one is impervious to a throat shot, eye shot or groin shot…the back of the knees, armpit and elbow crooks are great defaults as well, lets not forget the anus… yes I said it… the anus… There is no stitching that up.

Again, its dirty work that you have to get breast to breast to perform and it behooves anyone behind the blade to put every ounce of thier weight behind each strike of that blade…there is no fancy fencing about it. Get it in there so far that only bone or daylaight can stop you, twist it, rip it and repeat as necessary.
Also, how you hold the edged device will determine your level of success or lack there-of. Some well known edged tool instructors will advocate a firm fist. I disagree simply because blood,sweat and mucus are slippery and the last thing one wants is to hit a hard spot and drag the hand across ones own blade becuase there was nothing to stop it on your end. With an “ice-pick” grip we alway place the thumb on the butt regardless of what kind of pig sticker we are using to keep it from dragging if it gets caught up. For the conventional grip we like to mirror the same grip as best as we can… if the device permits(not double edged all the way down) we like to press the thumb along the spine of the blade, since not only does it help mitigat the possibility of it sliding, it also helps power assist ripping it out in whichever direction you choose.

I always love your post George. You have a knack for spinning my wheels.

Cheers.
