Best Self Defense Knife

For Everyday Carry

A knife isn’t necessarily your first thought when it comes to self defense. Most people think of other forms like martial arts to help keep you and your family safe from a perpetrator.

In some cases though, a weapon can be a vital part of your defense especially if you are facing a wild animal or multiple attackers. Specifically, having the best self defense knife can be a lifesaver in certain situations, especially if you have the right skills to use it.

If you’re in a hurry, here’s a quick look at my top 5 best folding knives for self defense.

There are several factors to consider when choosing a self defense knife and how to find one that fits your skills. Here are some tips on what to look for when choosing the best self defense knife for you and a few knife reviews to help you get started.


Accessibility is key for the best self defense knife to carry and, if you can’t draw your knife fast enough, you will be vulnerable to your attacker. The clothing you wear with your self defense knife is also important and will influence how you conceal your knife.

Long jackets are great for concealment, but can be a problem when you need quick access to your knife. Loose fitting clothing allows you to quickly access your knife in that critical moment. 


Concealment works hand in hand with accessibility. It is important to conceal your weapon, but if you can’t access it fast enough, it’s not going to do you any good. It’s important to remember that you should place your knife on the opposite side of your body from your dominant hand. That way someone that is right-handed can pull out a knife from the left side of your waistband.


Knives come in varying lengths, and the best knife for self defense should be between three and five inches. Larger knives like eight to nine-inch tactical knives are better served as a part of your survival gear or as a hunting knife.


The best self defense knife is either folding knives or fixed blade knives. A fixed blade knife is more functional than other types of knives and is very durable. Blade lengths vary on fixed blade knives, but you should look for one that fits inside your waistband for effective concealment that won’t sacrifice your comfort.

An assisted opening knife is the best folding knife for self defense since it has a blade that springs out when you start to open the blade. They are very portable and are easily carried inside your pants pocket. 

There are also other types of self defense knives like the Karambit knife that has a blade that is curved. This is an effective knife due to its unusual shape that can cause deep slashes that cause a lot of bleeding.

An OTF knife like the Benchmade Infidel, would also make a great self defense knife, you can easily deploy the blade with a touch of a button. However, you will need to check your state’s laws as there are very strict restrictions against these types of knives.


The orientation of the blade will depend on the function of the knife and the maker. There should be a cutting edge and point on the knife with a tip that is durable enough to withstand an impact as well as pierce through skin. Here are a few common types of blades that are used as self defense knives.

  • Drop point blades are very common, resist breaking, and are used for controlled cuts.
  • Clip point blades can also make controlled cuts and allow you to easily pierce or stab due to a tip that is sharper and thinner than the drop point blade. 
  • Spear point blades are also known as throwing knives. This durable blade looks symmetrical and can effortlessly stab or pierce an attacker.
  • Needlepoint blades have a double-edged allowing it to cut on both sides. This is a great self defense knife since its tip is located at the blade’s center and it is well known for its thrusting and stabbing abilities.
  • Reminiscent of a Japanese sword called a katana, the Tanto blade is versatile and is able to cut through an object with a large force. This is a perfect knife for self defense since it can easily slice, stab, and pierce your attacker.


Make sure that your knife has a good grip so you can easily protect yourself in a fight. The knife should be an extension of your body, and it won’t help in a fight if your knife has deep grooves that can be uncomfortable, especially if you have the habit of changing your grip often.


Self defense knives are commonly made from either stainless steel or high carbon steel. With a carbon steel knife, you will have a strong and durable knife that will retain its sharpness for a long time. However, they tend to rust, so you need to be prepared to oil it regularly to stop it from rusting.Stainless steel knives are rust-resistant and won’t corrode. They are weaker than carbon steel knives, so they will dull faster and require more sharpening.

Locking Mechanism

Only found on folding knives, the locking mechanism comes in multiple forms, here are a few of the more popular types used in modern edc pocket knives.

  • The Lockback mechanism locks into the notch on the back of the blade. This is a reliable and safe lock as your hands won’t be in the way if the blade closes accidentally.
  • A liner lock is a common folding knife lock and features a side spring bar that is placed on the same side as the blade edge. This is a good lock if you are only using one hand to grip the knife.
  • The frame lock mechanism is similar to the liner lock but features a separate metal liner instead of a spring bar. It creates lockout of the frame of the knife and folds similarly to a liner lock.
