The Ultimate Guide To Using Knives For Self Defense

What do you think about using knives for self-defense? There are a lot of talks these days about the importance of not only being able to use a knife offensively but also having the ability to defend against the blade. Even many of the traditional martial arts are implementing an edged weapon component to their curriculum.

These days, all you need to do is turn on the news and you will see why the importance of a knife used in self-defense has become a precedence. Criminals and terrorists are not only attacking the general public with an edged weapon. They are also targeting law enforcement with machete’s as well as other blades.

Knives for Self Defense: Here’s Why

Experience with Knives

I was first exposed to various methods of knife training in the United States Marine Corps. We practiced with bayonets as well as our Ka-Bar TDI law enforcement knife. These were two of the blades that were standard issue and always out with us on the field. We heard many war stories from our instructors about the value of being proficient with an edged weapon. Not only was it valid in trench warfare during World War I and II, but it has also been utilized by modern day special forces fighting terrorism.

Once my active duty tour in the Marines was over, I continued my education on utilizing knives for self-defense. My focus was on FMA (Filipino Martial Arts) and other methods coming out of Eastern Europe. Pulling movement patterns from both systems allowed me to gain a deeper understanding of how and when to deploy a blade during a combative situation. There are many similarities to any good knife fighting system. Finding one you will stick to and practice often is the advice I give anyone who is beginning their training.

Please keep in mind there are no winners when it comes to most knife confrontations. Hollywood and even YouTube martial artists demonstrate applications that look amazing on video. Although in real life, things are much messier and devastating than what most people realize is the truth. One of my teachers explained it to me this way…

“In most knife fights there are two outcomes, one fighter goes to the hospital while the other goes to the morgue.”

Folding Knives or Fixed Blade Knives for Self Defense

Just like most things in life, we all have different preferences and needs when it comes to the type of blade we choose to carry. We have those who prefer a folding knife they can easily conceal in their pocket. There are others that feel the only true fighting knife is one that features a fixed blade. The arguments on both sides are usually quite valid. However, there are laws and regulations, depending on your location, that will limit your choices to either one or the other.

I am currently based in New Jersey. Here, I am allowed to carry a folder as long as they meet certain specifications. If I were to get in my car and drive just 40 minutes away to New York City, my folding knife would be illegal but a fixed blade would be fine to carry. My point here is we may not be able to carry our preferred blade so it is always best to continually train with both types of knives.

How to Grip Knives for Self Defense

There are two main grips when it comes to the knife. There is the forward grip and the reverse grip. With the forward grip, the knife is usually tip up. With the reverse grip, the opposite occurs and the tip is down. There are different schools of thought as to which grip is best. It is true we may have a preferred grip for wielding a knife but in a self-defense situation, that choice may not be available.

In an ideal scenario, you will be able to deploy your blade in your preferred grip. However, when SHTF during a combative encounter, your ideal grip may not be an option. In a struggle, a blade may end up on the ground. When you retrieve that blade it may be in either a reverse or forward grip. Knowing we cannot always get to our ideal grip, it is imperative you train with both positions in mind.

Thinking About Your Range

There are four main ranges when it comes to combative applications with the knife. The varied ranges are:

  • Close Range – Within this range, you can elbow, knee, and headbutt your attacker.

  • Mid Range – In mid-range, your empty hand can touch your opponent during an encounter when fully extended.

  • Long Range – In the long range, your empty hand is unable to touch your opponent when extended.

  • Floor or Wall – This last range comes into effect once one plane of motion is removed. This occurs when up against a wall or on the floor.

The way we attack and defend against the knife has a lot to do with the range we are in. As an example, when I am in mid range, I will need to use my empty hand to “check” my opponent’s strike. If I do not, I will get cut during their follow through with the knife because of our short distance from each other. If we are in long range, there is no need to use my empty hand to check because my opponent will be too far from me to actually cause damage to my vitals.

Attacking with Eight Angles

When it comes to teaching offensive movement with a knife, there needs to be a certain language spoken by the teacher and the student. Instead of using complicated language to convey a movement, we use angles numbered from one to eight. Some teachers choose to utilize more angles while other instructors opt for less. Neither option is superior to each other, and it is completely up to the teacher’s discretion.

If we were to use our neckline as an example, a knife strike coming diagonally from the right would be called an angle one. A backhand coming to the right side of the neck on a diagonal would be an angle two. Utilizing a simple number system not only simplifies the learning process but it allows much less processing time to speed up their movements.
