A Simple Buying Guide To Determine The Best Self Defense Knife

A self-defense knife is a special breed of knife. Usually, they are tactical knives specifically designed to assist you in a self-defense situation. While no one wants to find themselves in a situation where they feel endangered or threatened, the right self-defense knife can help send the message that you aren’t an easy target. Should you be forced to use or display a self-defense knife, the best ones are made for quick retrieval and instant deployment. As such, many selfdefense knives fold and are easy to conceal. 

When selecting your personal self-defense knife, there are many things to take into consideration. We will discuss several of the most important factors and features in more detail below. But first, let’s take another look at the advantages of finding a high-quality, durable self-defense knife

What To Pay Attention To When Buying A Self Defense Knife

There are some different styles, sizes and functions among self-defense knives. To help you decide which is right for you, we’re going to lay out some of the most important things to consider. The best self-defense knife is one that you can carry without thinking about it. It’s also one that you’re comfortable carrying, handling and wearing.

Folding Knife VS Fixed Blade

There are two main styles of knife you can choose from. You’ve seen multiple examples of both in our list above. People have their own preferences and feel very passionately about why one knife style is better than the other. At the end of the day, it’s up to you to decide whether you want a fixed blade or a folding knife. There’s no right or wrong answer when it comes to choosing between folding of fixed blade knives. There are people on both sides of the argument who swear by the efficacy and quality of their knives. 

Folding knives can be carried in the pocket for easy access. They’re easy for you to conceal and easy for you to grab in an emergency. Because they’re discreet, you’ve got the element of surprise if you draw this knife on an assailant. There’s no need to compromise on quality, because many folding knives are just as sturdy and strong as fixed blade knives. They tend to be smaller and less obvious. But their size can be an advantage, too. Some people are just more comfortable working with a more compact knife.

Fixed blade knives do not fold, which is precisely why some people believe they are better suited to self-defense. The idea is that the split-second it takes to unfold a knife may make all the difference. Fixed blade knives are typically stronger, longer, and more efficient. Many believe that drawing one of these knives from a sheath is much faster and more effective than having to unfold a pocket-knife in an emergency. Cleaning is also easier with a fixed blade knife because you don’t have to worry about the casing.

Once you’ve chosen the best style for you, there are few other things to keep in mind.


Larger knives can be problematic for a lot of reasons. Mainly, you’re less likely to carry a heavy or bulky knife around on a daily basis. And since self-defense knives are designed to help you in emergencies that cannot be foreseen, you have to carry one consistently for it to be of any use. A knife doesn’t have to be large or heavy to be effective. A larger knife might make you feel more in control, but a small folding knife can be just as strong and durable as some of its longer counterparts.

The bigger your blade is, the more trouble you’ll have wielding it. It’s also more likely to be lethal, which is something you don’t want to take lightly. It’s far more likely that you want to distract someone than cause them any significant harm. Again, smaller knives are easier to conceal and there is a clear advantage to that. Very small knives may not be effective, so you want to find a knife that’s somewhere in between. You don’t want something so small as to be ineffectual. But you don’t want something so large and heavy you can’t use it accurately or carry it without giving yourself away.


Importantly, you’ll want to make sure you’re abiding by your local state laws when you set out to carry a self-defense knife. Different states have different laws, standards and requirements. Even in self-defense circumstances, it’s possible to break the law by carrying an item that’s technically illegal or forbidden. For example, it’s highly illegal to carry an automatic knife in many states.

The last thing you want to do is break the law when trying to defend yourself from a violent criminal. You’ll wind up opening yourself up to a world of legal woes and possible imprisonment. A quick Google search can clue you in to the specific requirements and legalities in your state. And just remember that different states have different rules and regulations. If you travel, check the laws in the area you’re about to visit.

If you’re selecting a knife for everyday carry, it’s very important to make sure that your particular self-defense knife meets your state’s requirements. 

Why Choose A Knife For Self-defense?

Experts recommend knives for self-defense for many reasons. First and foremost, guns are not for everyone. Most people in a self-defense situation are not aiming to mortally wound the other individual. They are looking to surprise, distract, thwart, or, in extreme cases, incapacitate them. Knives are a good choice for all of these goals and are easier to purchase than guns. They’re also easy to conceal, which is a huge benefit for any self-defense item. And in close quarters, the best self-defense knife is a smart option for accessibility and ease of use. While you’ll need to research your state laws regarding self-defense knives, they’re still easily to carry than guns.

Self-defense knives are knives created with defense purposes in mind. They’re often easy to conceal and lightweight. The best self-defense knives equip you with the means to handle yourself in the unlikely event that you enter into a critical defense situation. They can look menacing, and sometimes it’s enough to be able to just brandish a knife. The ultimate goal in carrying a knife is to diffuse the situation and walk away unharmed while personally obeying the law.

Advantages Of A Self Defense Knife

One of the most important advantages of owning a self-defense knife is that knives are effective in close combat. These knives are intended for use in a defensive manner, and always as a last resort. The right self-defense knife can save your life, deter an assailant and thwart someone’s plans to do you harm. Carrying a knife can give you peace of mind. The right self-defense knife provides you with an immediate defense option should you find yourself in an unthinkable situation.

Knives are effective in close-range encounters, they don’t threaten bystanders, and they rarely miss their mark. With a little practice and education, you can learn to use your self-defense knife effectively without any special training or skills. Most assailants won’t expect you to be carrying a knife, so the element of surprise alone can successfully end the attack.

But owning a self-defense knife is only an advantage if you know how to use it. Whichever knife you eventually choose, you’ll want to make sure to do your research on how to stand, how to hold your knife, and when it’s appropriate to draw your knife in self-defense. If you know anyone who has served in the military or in law enforcement, they are an excellent resource for this kind of information. Once you get your knife, you can focus on learning how to carry and use it. But for now, let’s take a look at the characteristics you should keep in mind when shopping for your knife.

Frequently Asked Questions (FAQs)

What’s better for self-defense: a folding knife or a fixed blade knife?

The debate over folding VS fixed blade is a fierce one. Ultimately, it all comes down to personal preference. Some people prefer the compact, lightweight, easily concealable nature of a folding knife. Others insist on the fixed blade knife for its immediate availability and its tendency to be heftier and stronger. Find a knife that you feel comfortable and confident holding, wielding, and quickly accessing. Whichever knife feels most natural and intuitive is the best knife for you.

What kind of knives do Navy SEALs use?

Special Forces use a wide variety of knives, mostly fixed blade, and mostly with no civilian equivalent. Many of the knives these warriors use are too deadly and dangerous to be suitable for civilian hands. However, dagger-type fixed blade knives are popular for Special Forces hand-to-hand combat, and there are some similar knives on our list.

What makes a good self-defense knife?

A good self-defense knife is easily concealed. If it’s obvious that you’re carrying a knife, you lose the element of surprise and might actually invite unwanted attention and aggression. Another aspect of a good self-defense knife is that you can access it quickly and seamlessly. If you can’t deploy your knife in an instant, it’s no good to you in an emergency situation. Everything else, features and styles, is secondary to those two qualities.

Is it legal to use a knife in self-defense?

You’ll need to confirm this with your local government and your state’s specific laws. Certain knives are illegal in certain states, and the rules and guidelines vary. Make sure you’re carrying a knife that meets the standards and qualifications set forth by your state. It’s legal to defend yourself against violent assault, but if you’re using an illegal weapon or device, you’re still going to get yourself into trouble. Look for the guides on traveling with knives at the website of the TSA.

Are self-defense knives really worth the price? What if I never use it?

A self-defense knife is an item you hope to never need. However, many of the self-defense knives listed above can be used for other, more practical purposes. Whether you use your self-defense knife for other tasks or not, it’s worth its value, even if you never use it. Just having a self-defense knife sets you up to be able to defend yourself, giving you peace of mind. Just showing that you have a knife is enough to deter most people. So in the rare event that you have to brandish your knife, it’s possible that it could save your life without ever being put to use.

Final Verdict

There’s a lot to take into consideration when looking for the best self-defense knife. Outside of varying styles, you want to weigh quality, durability and efficacy. While we hope you never have to use your knife for self-defense purposes, the above knives are great options for “just in case”.

 That being said, if we had to choose a top self-defense knife from the list, it would be the Gerber StrongArm Fixed Blade Knife. This full tang, matte-black self-defense knife is lightweight, sturdy and durable. The handle gives superb grip for ease of use and confident maneuvering.

The rubberized diamond texture grip of the handle is both comfortable and durable in any kind of weather. Because they’ve been making survival knives for the US Military since 1968, you know Gerber can be counted on to produce a high-quality knife that stands the test of time. 

This knife also gets bonus points for versatility. It’s a tactical knife with a sheath that can be mounted several ways. What’s more, it looks great with its full tang fine-edge blade in black ceramic coating. You can expect a long life from the blade since it’s corrosion proof and made to last. All in all, this knife is a knock-out. Surprisingly, it’s also one of the most affordable knives on the list. And while we hope you never have to use it for its intended purposes, we know you’ll appreciate the Gerber StrongArm for its outstanding craftsmanship and unmatched quality.
