The 10 Best Self-Defense Knives 2023 Reviews

The best thing you can do for your safety, we can all agree, is not to put yourself in a dangerous situation. But if you find yourself in such a situation, it’s good to have a weapon you can use. A good self-defense knife can act in your favor in this case.

The self-defense knife is different from the combat knife. With the self-defense one, your objective is not to attack or kill but to incapacitate or disable the assailant so you can escape.

Typically with self-defense knives, a slashing motion is preferred to a stabbing one because it has a better chance to cut through muscles and tendons but a lesser probability of killing.

Knife blades come in a variety of types. Some of them are superior than others in terms of self-defense. The blade’s sharpness is another important consideration. Make careful to keep your knife as sharp as you can if you want to use it for self-defense (or any other duty other than sitting in a case, for that matter).

You also have the option of a straight or serrated blade. It depends on your preference since they each have various advantages and disadvantages. Remember that serrated blades are more threatening and will deter an assailant because of this. But in order to get a tactical edge, it is strongly advised to hide your knife for as long as you can.

In most cases, your opponent shouldn’t know what weapon do you have at your disposition. When defending yourself with a cold steel knife, you should conceal it until the last moment possible.

It’s an excellent job if you succeed in scaring the assailant away, but if you can’t, and the law enforcement doesn’t come, you will have to fight him for real.

Is a knife good for home defense?

Don’t forget that a knife is as good as the person that wields it. Besides getting the right blade, you should also put aside time to practice drawing and handling it.

Slashing motions are ideal if you have enough space to unfold your actions. But you will have to use the stabbing if you are in a tight space if the attacker is pressing down on you. Simply make sure the blade is not too long to prevent yourself from overextending.

A good knife with a sharp edge is ideal for home defense. There are several huge fixed blade knives that are an excellent alternative to folding knives. Similar to the self-defense pocket knives you carry with you when out in nature, you must maintain them by keeping them sharp and accessible.

What knives do Navy SEALs use?

Many people look up to the special forces for knife brands, and that’s something manufacturers tend to use to sell their products. That’s why many of them send their knives to the United States Marine Corps, the Special Air Service, or the Navy SEALs, hoping that they’ll like and use them.

After all, if they start using them, the company will be able to sell more products.

So, what are the knives Navy SEALs use? Most of all, sharp ones.

Jokes aside, as it happens with all users, it is more of a personal preference. The primary mechanism for choosing a knife is trial-and-error. The old-timers usually preferred standard-issue KABAR’s or other OTS dive knives, but now you can find all kinds of OTS brands in a guy’s kit: SOG, Gerber, Ontario, SDK, etc.

The Navy SEALs will use any sturdy knife that holds its edge reliably and has a strong resistance to salt corrosion. So there is a big room for choosing combat knives as well as self-defense knives.

How long should a self-defense knife be?

There are two factors on which the length of the self-defense blade depends – basic dynamics and the possibility of hiding it. The optimal self-defense knife is several inches long – easy to conceal, and easy to wield.

Another important question is whether to choose a fixed blade or a folding knife. Both of them have their pros and cons.

For example, fixed blades are stronger than folding ones but more challenging to conceal. You could carry a few defense knives on you far easier if they are folding knives, but it will be more difficult for you to draw and unfold one if needed.

The ideal self-defense knife has a fixed blade or a folding blade that is no more than 5″ inches long for easier storage, concealing, and wielding. Moreover, some states have knife laws restricting blade length. So have that in mind, especially if you don’t want to have any problems with law enforcement.
