Features To Consider When Buying A Self Defense Knife

When you’ve finally decided to get a knife for self-defense, the next logical step would be to understand what features to look out for when you go to pick one.

An experienced knife user would understand how important things like the quality of the blade but a newbie would probably just go for the deadliest looking one.

However, all of us need to know how all of the features work to make the knife efficient. We’re going to explain all of these things simply so that you can know which feature will be your top priority when choosing the knife.

Types Of Blade

There are many different types of blades but we’ll just mention some of the ones we’ve reviewed here. We’ll start with the karambit blade which is one of the most effective self-defense blades you can get. It’s claw shape with a fine edge and sharp tip gives it an advantage for stabbing and slashing.

The drop point and spear point blades are almost similar to each other in that the blades converge at a sharp tip. These types of blades are very effective in stabbing and ripping.

However, a narrow tip such as the clip point blades can break easily because the tip may be weak. The tanto style is also narrow but it has the advantage of having a chisel style edge that is very tough for repeated stabbing action.

Blade Materials

Stainless steel is one of the best materials for knives because it’s easy to sharpen and has good corrosion resistance. It gets dull often but it’s the best for combat, self-defense, and general utility use.

There are different grades of stainless steel which affects the overall price of the blade. The cheaper variations are still good quality blades but with less edge retention and straightness. They make decent options for the budget-conscious buyer or if the knife has no other use than self-defense.

Handles

The size and shape of the handle will affect how well your knife will be effective. A comfortable grip on your handle will give you control when using the knife and also make it harder for your attacker to overpower you.

A large handle on a small hand will be easy to lose in a fight. Likewise, a small handle may cause injuries when your fingers run into the blade.

Also, there are various handle materials to consider but the G-10 scales are the most common. G-10 is a highly-pressurized epoxy resin laminate that provides a durable and lightweight material.

It is hard-wearing, impervious to wetness, and easily customizable which makes it a top choice over other materials for knife manufacturers world over.

Fixed Blades

When picking a knife for self-defense and survival, the popular conception is that fixed blade knives are more reliable than folders. That may be true but think about how unpractical it would be to go jogging with a fixed blade knife tucked in your gym shorts.

Not the most comforting thought, is it? But, let’s look at the advantage that the fixed blade knives have over folders to see why the experts would recommend it.

Top on the list is that you don’t have to depend on the reliability of the opening mechanism of folding knives when you come across a mugger. Realistically speaking, it takes quite a bit of practice to get any of the one-handed deploy tricks working effortlessly for you. So you see, having a ready knife should be a priority.

Folding Knives Opening Mechanisms

Folders on the other hand are more compact and easier to carry, especially in a concealed manner. That alone makes them preferable by ordinary users because you can carry a folded knife in the pocket with you at all times, if necessary.

Ultimately, you’ll need a good quality knife that maintains the locking mechanism in position so that it doesn’t deploy unexpectedly in your pocket and cause an injury.

Folding knives have different methods for opening the blade. Some of the most popular methods include the Emerson Wave which utilizes a hook at the spine of the blade to open it. Others have a flipper feature that you push with your index finger and others have a thumbhole on the blade which uses the thumb to open.

All of these methods require some practice for you to be able to utilize effectively.

Conclusion

Ultimately, your personal preference will decide which kind of blade to go for. From experience, just having the knife will not be enough unless you know how to use it effectively.

So if this is your first knife, we recommend getting some training to use it for your safety and protection.

We hope you’ll be able to get the best knife for self-defense from our list. And just to remind you, our favorite is the Al Mar Sere 2000 which has been touted by most users as one of the best tactical knives in the market.
