A knife is an excellent self-defense weapon. It is not just a sharp extension of your arm to help in unexpected situations, but there is also some psychological power behind it. According to experts, it seems people tend to be more afraid of knives. Knives outweigh guns in terms of fear, but they come with many other extras too.

Sometimes, this fear is stimulated by the fear of getting stabbed. If you think about it, a stab wound will probably be more painful than a gun wound. On the other hand, some people may also have experience with such wounds. A criminal with years of activity has probably been through such conflicts before.

Now, deciding on the best knife for self-defense could be a bit problematic because you have no idea where to start. There is no such category. No manufacturer designs knives for self-defense. Pretty much everything is related to your personal preferences, as well as your skills. At this point, if used correctly, pretty much any knife could make a good self-defense weapon – even that long bread knife in the drawer.

Some may imagine that carrying a gun could be a better option, but this is not the case. Of course, a gun can harm someone from a long distance, but luckily, many fights do not involve guns. A knife is simply more practical. Besides, laws vary widely, but they are certainly kinder when it comes to knives. Guns are banned pretty much everywhere except the USA.

It pays off researching current laws in your area. Laws vary widely from one country to another, as well as from one state to another. There are different regulations regarding the type of knife, the blade length, and so on, so you need to make this decision with the law in mind.

Then, you need to understand that when bought for self-defense purposes, a knife is no longer a tool. It becomes a weapon. It is limited to your skill, yet some knives provide more forgiveness than others. Moreover, it features some risks as well, you will have to accept them.
