Get the Best Self Defense Knives with this Guide!

You are trying to decide which knife would be best for self-defense? Not sure about what length, blade material, or weight you’ll need? This is the post for you!
We’ll walk you through the ins and outs of choosing the perfect self-defense knives so that there are no surprises when it comes time to make your purchase. It’s not an easy decision. There are so many options now on the market and with all this information, how do you know where to start? Here are a few things to keep in your mind:
- Blade Length
The first thing you want is a legal blade length. That means you need to check your state’s laws for specifics. Choosing a knife that’s too long can make it easier for you to get in trouble if you’re arrested and charged with a crime.
If your state allows blade lengths of 3 inches or less, the first thing we’d recommend is the pocket knife. It’s a safe pick because it has a 3-inch blade, is made of strong steel, will last forever, and comes in a few dollars so there are no worries if it gets lost or stolen. We also love that it’s got an affordable price tag but looks like a million bucks so it doesn’t scream “cheap”.
- Blade Material
Now let’s look at blade material. Nearly every blade is either stainless steel or high carbon. Which is better? It’s a matter of preference. Both have some pros and cons. Stainless steel is more of a “maintainable” metal meaning it’s easier to keep clean and disinfected if you’re using your knife on a regular basis. High Carbon blades are tougher and can rust quicker, but usually cost less.
- Knife Weight
Having no experience in knife fighting or self-defense? You probably want a blade that weighs less than 3 ounces so it doesn’t weigh down your pocket or leave you exhausted while holding the knife up to fight back if you’re being attacked by an assailant.
Some manufacturers make knives that weigh in at less than a pound so you’re not carrying any more weight than you need. Select knives that are lightweight and perfect for your lifestyle.
- Overall Size
Now let’s talk about knife length. There are two types of lengths we like to recommend based on what you’re going to be using the knife for. If you plan on cutting rope, digging tunnels, or digging holes at a campsite, you’ll want a 4-inch blade that’s 3 inches long from tip to handle.
Also, if you’re going to carry this knife with you all the time, you’ll want a blade that’s 5 inches in length to give you more control over your weapon. On the other hand, if you’re planning on using this knife for self-defense, we recommend a 3-inch blade.
What about those double-edged knives? There’s a rumor that it makes these knives sharper but in reality, it’s just so the knife can have an overall longer blade. We’d save your money and opt for a single-edged knife instead. It’ll be cheaper and easier to sharpen when it gets dull.
Great Way to Protect Yourself!
A defense knife is a great way for the average person to be able to protect themselves. These self-defense knives can range from small, concealable items like hidden keychain knives, to bigger, intimidating blades that give the user more of an advantage over an assailant.
Either way, people who typically don’t carry a weapon will often find these handy self-defense weapons come in handy. In most states, it’s illegal to carry a concealed weapon without the proper permit. This means that someone with a concealed weapon or knife could be arrested if they’re caught without their permit or ID.
Having an easily concealable defensive knife can help avoid these issues for people who are not comfortable carrying around a weapon but still want some security. Some defense knives have non-lethal ways of protecting like stun guns that deliver a powerful enough shock to temporarily immobilize an assailant.
