Best Knife for Self Defence | Guide & Reviews | 2024

Many of us worry about falling foul of thieves and attackers, so a self-defence knife is a good item to invest in. Provided your local jurisdiction allows you to carry a concealed weapon, a self-defence knife can reassure you and bring you peace of mind.

When selecting the best knife for self-defence, there a key things you need to be thinking about. A self-defence knife should be easy to carry and conceal. If you are opting for a folding knife, the blade should also be quick to deploy and secure when retracted.

Need some help selecting the best self-defence knife for your needs? Our guide is on hand to provide you with all the things you need to consider when choosing the best knife for self-defence.

Types of Knife

When selecting self-defence weapons, you have two main choices of knife to consider. The most popular option is a folding knife. This type of knife includes a blade that is concealed within a handle. When you need to use your knife, you simply press a button on the handle exterior to deploy the blade.

The advantage of folding knives is that they are far easier to conceal and can be kept in pockets or boots. Provided you have purchased a decent product, folding knives can be an effective option. However, folding knives have some drawbacks. For one, they can be less sturdy than fixed blade knives and you may struggle to put substantial force behind the blade. Folding knives should also feature a reliable liner lock that keeps the retracted blade within the handle when it is not being used. The handles of folding knives are also fairly limited, with minimal finger and thumb grooves.

A fixed blade knife can be more difficult to conceal, but they are the stronger option. Because the knife and handle are fully integrated, you can put more pressure behind the blade without the worry of the blade breaking free of the handle. Although they are less discreet than folding knives, you can opt for a shorter overall weapon that can be kept in a sheath without drawing too much attention. Many fixed blade knives also include a lanyard hole at the end of the handle, allowing you to keep the weapon around your neck.

Blade Varieties

If you are not that proficient at wielding a knife, you should consider purchasing a weapon with a dual edge blade. Unlike other types of blade, a dual edge will cause damage no matter which side makes contact with an attacker. This means you do not need to worry too much about knife technique. A serrated blade will cause more damage than a dual edge weapon, although you will need to ensure it makes direct contact in order to deter an assailant. You may also want to think about the point of the blade itself. If you want to use your knife for wider applications, such as hunting, you should ensure the blade variety is designed for broader use.


Regardless of what type of knife you go for, you should make sure the blade is of a high-quality material. Stainless steel is the preferred choice of material when it comes to blade composition. This material is very durable and will ensure excellent edge retention. If you want a blade that will last for a longer period of time, look for knives that include a coated finish. This will protect against corrosion and require you to dedicate less time to blade maintenance. Handle material is also something you need to think about. Many knives will include an aluminium handle. This will bring down the carrying weight of your weapon substantially. However, any good handle should allow for a firm grip. Rubber inserts are a good idea as they allow you to maintain a good grip, even when using your knife in wet conditions. It also means you can maintain a firm grip on your knife with clammy hands.
