Here’s an awesome choice if you’re a little style-minded – this knife is exceptionally attractive. Not only that, but it’s also got class-leading durability and top-of-the-line performance. If the hefty price tag doesn’t faze you then this might be the best self defense knife on the market.

How to Find the Best Knife for Protection

Self-defense knives are not supposed to be decorations for your wall; they are mean machines with a thirst for protective intimidation. In most cases, a knife is a valuable tool that probably looks good either in a kitchen or on a dining room table somewhere, but not this type of knife. It doesn’t matter what a self-defense knife looks like or feels like – Does it do the job?

If you find yourself in a sticky situation, all that matters is, “will this thing save my life?” There are a couple of crucial points that you shouldn’t let slide when it comes to self-defense; note that appearance is not one of them. Let’s have a look at what you should consider when searching for a self-defense knife.


If you need to protect yourself from a person who is attacking you, to steal or otherwise, and you whip out a tiny little pocket knife, the pursuers might laugh. Now, if you were to yank out a potent dagger-like military-type weapon, then they may leave you alone without starting a brawl.


If it’s too late and you have no other choice but to defend yourself, then you’ll want something made of light materials and high strength so that it’s easy to operate and handle. The handle needs to withstand a large amount of force, with a sturdy grip that will ensure you don’t slip or, even worse, that it doesn’t get taken away and used against you.


When something gets the jump on you, with no warning, you’re going to need to access your knife very quickly, so it’s essential to get something that you can have ready at any moment’s call.

Frequently Asked Questions (FAQ)

Q: Is a Fixed Blade or Folding Blade Better?

A: A folding blade is easier to conceal, but it might not be as intense or intimidating. A fixed blade will give you a more intimidating presence and will offer you more durability. The problem with fixed blades is that they can be slow to draw, especially if they are in a tight sheath, whereas a folding blade can be flicked open in no time.

Q: Is It Illegal to Have a Knife on Me in Public?

A: If your local laws say so. Most of these knives shouldn’t be a problem to carry around because they are small and concealable. Automatic flip knives are illegal in several different places, so be aware of what you choose to buy in this regard.

Q: Is a Self-Defense Knife the Same as a Military Knife?

A: Army knives are a lot larger and more lethal. They have similar properties but are not equivalent to any of the knives on this list. Special forces usually use fixed blades for effective hand-to-hand combat; folding blades are more for civilian self-defense or multi-utility purposes.
