How to Choose the Best Self-Defense Knife

Although unfortunate, it is important to understand the world we live in is not entirely safe. Crime happens, in some places more than others, and the police will not always be there to protect you. That is why having a self-defense knife is important. However, there are many knives on the market, and it may be difficult to choose the “best”. I will look over the many attributes of knives and decide the best one for self-defense.

What Is the Self Defence Knife?

A self-defense knife I quite self-explanatory; it is a knife primarily used for defense against attackers. Although it is best to try and run immediately when you realize you are in a bad situation, this is not always possible. Although unarmed self-defense training and keeping away from bad areas will limit risk, a self-defense knife is simply an additional level of security.

What is the Purpose of Your Best Self Defence Knife?

The main purpose of my self-defense knife is to prevent an attacker from harming you, as well as giving the user an opening to flee, get to a safe place, and get help. For the former, the knife needs to keep potential attackers at a difference and well as interfering with attacks from the opponent. Additionally, the knife, once it is pulled out, causes most potential attackers to flee.

Considering the Overall Length of the Self Defence Knife

There is two main classifications of the knife, fixed blade or folding. The former is a simple knife with no mechanical pieces. The latter is able to fold in on itself. Both have their benefits and disadvantages.

Fixed: Fixed blade knives are sturdier and thus more powerful. As said before, folding knives can cut the space it takes up by half, making it able to be more easily hidden. Much of the choice in this situation is based on law, as it limits what can be used as well as many other attributes. For this essay, it will be assumed laws will not get in the way, and the knife created will be one based on what would make it the best for self-defense. When trying to create the best self-defense knife, fixed blade is the way to go.

Folding: The problem with folding knives is the time it takes to ready it, which is the time which you are vulnerable to attackers. Additionally, the mechanics may jam or another problem occurs, and what was once your protection becomes dead weight. Read More: Best Folding Knife Under $200

Measure the Blade Length According to You Requirement

Now that the type of knife has been determined, let us move onto weight. To optimize a self-defense knife, it should be as long as possible, while not being unwieldy. This means additional reach for the user, which can affect attackers before they get too close. For a fixed blade, one that is 6 inches long fits quite well.

Although it was decided a folding knife wouldn’t be the best type, a length should still be determined. The befit of a surprise that comes with a folding knife is very important and should be maintained. A 4-inch folding knife would be both hidden and have the length to defend

Since the blade wanted is one that keeps an attacker at bay, it should be as long as possible. However, smaller or less experienced users may not be able to, so smaller options are provided below. Included are both full knife and length of the blade.

Small Blades: Small folding blades will 4 inches when extended, with a blade of 2 inches. This weapon will be very prone to breaking, especially is defending against attack. It does allow for surprise attack due to its small nature. Small fixed blades will be 5.5 inches, 3 of them being the blade. This will be more study than its folding knife counterpart and will be hidden better than larger fixed blades.

Medium Blades: Medium folding knives will be 5 inches when the knife is out, 2.5 when folded. It remains hidden while allowing strengthening of the mechanics. A medium fixed blade will be 6.5 inches, with the blade being 3.5 inches long. This way it is easy to hold for most while still having power behind it.

Large Blades: Large folding knives will have a 3-inch blade; when the handle is added it is six inches. Although less subtle than smaller folding knives, it is much more powerful. A large fixed blade will be 8 inches, 5 being the blade. This will have the largest reach and most power behind it. This would be the most effective length to use.

Choosing the Blade Material

Blade material is very important, and in this case, it is the durability we want. This will prevent the blade from failing when encountering an attacker. When researching, the best I could find that matches this description is carbon steel, which is known for its sturdiness. Additionally, it keeps its edge for a while one to has been sharpened. It is, however, prone to rust if not taken care of. Thus, it will be important for the user to check the knife daily, to make sure it will withstand attack.

Selecting the Blade Shape or Tip

Seeing as this is a self-defense knife, I will be looking for blade shapes/tips that prioritize slicing to keep foes back; additionally, sturdiness will also be important.

Drop Point: Drop point has the non-sharp side curve towards the point. This causes the tip to be stronger and gives it a long, slicing edge. Due to this wider tip, it is not effective at piercing.

Clip Point: Clip point has the unsharpened edge start off straight but goes to the tip halfway. This allows to pierce and slice very well. This design is thinner, so it is weaker.

Spear Point: Spearpoint has both edges curve to the center in the same way; if single edged the point won’t be as sharp. This sharp point is not great for the slice but is meant for piercing.

Scandi Point: Scandi point starts of straight on both sides but curves after a while. This blade takes a long time to sharpen but is easy to be consistent. It isn’t good at slicing. 

Hollow Point: Hollow point has it edges go to the point in a concave fashion. Due to the lightness of the design, it is good for slicing, but it is very delicate.

Full Convex: Full convex has a gentle curve on both edges starting at the bottom of the blade. Its design makes it durable and able to keep its edge. However, it takes a long time to sharpen.

Blade Spine: The spine of the knife is the opposite of the sharp edge, meaning it is facing the uses. The self-defense knife should not be double-edged, as if the knife if knocked back when block, the user could cut themselves. Additionally, make sure the spine is solid, as it may be used to block or attack in a pinch.

Selecting the Blade Edge

The blade edge is what you will be used against an adversary, whether it be making slices to try and chase the attacker away or protecting against attacks. Thus, it is important to choose whether the blade edge is going to be serrated or plain.

Plain Edge: A plain edge is straight, simple, and is very versatile. It is easy to sharpen and is quite terrifying to potential adversaries if wielded intelligently. There potential for slicing, which drives foes away, and ability to reflect incoming attacks on its smooth surface, make it the best choice for our self-defense knife. It does need to be said that slicing with it isn’t likely to penetrate thick surfaces.

Serrated or Saw-toothed Edge: Serrated edges are good at one thing, that being to cut through tough material. This may originally seem like a perfect addition to the self-defense knife, seeing as attackers may wear hoodies, leather jackets, or other thick materials. However, I will not suggest it, as it is like that a serrated blade would get stuck, whether on clothes or flesh, disarming you and leave you with less defense. 

Combination or Partially Serrated Edge: Simply put, a combination is when the blade edge has part serrated, usually the lower portion, and part plain, often situated above the serrated section. Additionally, the blade edge can be plain and the knife spine is serrated. As stated earlier, the spine will be used for something else, so this option is not suggested, as well as serrated edges tendency to get stuck. Also, you need the best knife sharpening system for honing the serrated edge blade.

Knife Tang For Fixed Blade

A knife tang is the part of the blade within the handle. Depending on how much is there, a knife can be severely weakened, especially when made to defend against attack. The sturdiest, and the one I suggest is the full tang, which has a solid piece of metal that goes all the way from the base or the blade to the pommel. This makes the knife extremely strong. The other types, partial tang and rat-tail, are partial versions of the full tang, which are weaker and not suggested.

Considering the Knife Handle

The knife handle is what makes the blade useable, so its quality is extremely important. Make sure it is comfortable and fits in your hand. A blade of about 3.5 inches works for many people. Additionally, look for guards that can be added to provide greater protection. Example include knuckle guards, which protects the finger while helping the user make stronger punches. An upward angled quillion can cat blades and protect the hand. Make sure there is some soft padding between your hand and the handle; this to absorb shock when blocking blows. Making the handle out of a sturdy material, such as steel, also help by making the knife a more solid object. Lastly, make sure it fits snuggly in your grip, both with gloves and not, as that can have a large impact on how tightly you hold onto the knife.

Solid Pommel of the Knife Handle

The solid pommel within out self-defense knife is important for many reasons. Firstly, it is the main component of keeping the handle together, so its quality is important. Most of this comes down to the tang and knife material, which has been discussed. Secondly, a pommel can act as a blunt method of attacking, fending off attackers without resorting to bloodshed.

Easy To Carry

Since this knife will be used for self-defense, it must be carried on the person to be effective. This is more likely if the knife is easy to carry. Since the suggested type was fixed blade, the best way to carry it is in a sheath. Make sure that it holds the knife securely yet is easy to draw the knife out of. Every second count in self-defense.

Final Verdict

The best attributes for a self-defense knife is to be fixed, 8-inch-long knife with a 5-inch carbon steel blade. The blade will have a drop point, with a plain edge. The knife will have a full tang, which acts as a strong pommel.
