How To Defend Yourself with a Dagger Knife?

Have you ever wondered how a dagger knife is used in self-defense? This is the question that many people ask themselves, and it's important to know if dagger knives will be effective for your needs. Dagger knives can be used as a defensive weapon or they can be thrown at an attacker. It all depends on what tactic you decide to go with. In this article, we're going to discuss dagger knife defense tactics so that you'll know which one would work best for your situation!

What is a Dagger Knife?

The best dagger knife has an exalted standing among fighting knives that few other blade designs can match. Daggers have long been recognized as potent weapons, whether they earned it or not. However, for current self-defense, past repute is insufficient. We need actual performance for self-defense. To that aim, let's look at what makes a good dagger and how to use the right skills and techniques to take advantage of those qualities. A real double-edged knife capable of substantial cutting performance with either edge is defined as a dagger. Single-edged knives with fake edges—sharpened partial edges on the blade's spine—also technically qualify under that description.

Knife’s Edge Geometry

Pay special attention to the knife's edge geometry, regardless of your choice. Its cutting blades must be somewhat thin and sharp to cut well. Daggers present a problem since double edges necessitate shorter primary bevels on each edge than single-edged blades. As a result, the obtuseness of the edge angle increases as the slope lengthens and the cutting capacity decreases. This flaw affected several iconic daggers, including the well-known FairbairnSykes commando knife.

If a folder isn't an option, a fixed blade knife or cold steel knives is the only alternative. Fixed blade knives are more straightforward, stronger, and faster than folding knives, but they might be difficult to use from comfort and legal standpoint. It's almost like placing two single-edged knives spine to spine to make a high-performance dagger knife blade. Long bevels and acute terminal-edge geometry should be present on both cutting edges. This is aided by broad blades, thinner blade stock, and hollow-ground bevels.

Design Considerations

With a few exceptions, folding knives do not lend themselves well to double edges. When the knife is closed, the blade's spine protrudes typically from the handle. If it were sharpened, a sharp edge would be exposed even when the knife was closed, making carrying and deploying it perilous. Therefore, a design that permits the blade to fold thoroughly within the handle is the only way to carry a double-edged folder safely. Balisongs are the finest at this with good quality. 

The Applegate-Fairbairn Folder's early bespoke variants were double-edged, but most folder designs don't allow it.

Cutting using the back edge of the blade puts a lot of stress on the lock mechanism, which is another concern with double-edged folders. You could be seriously hurt if it isn't up to the task and the folder "lives up to its name" at the wrong time. If a folder isn't an option, a fixed blade is the only alternative. Fixed blade knives are more straightforward, stronger, and faster than folding knives, but they might be difficult to use from comfort and legal standpoint.


Many countries make it unlawful to carry double-edged knives, so planning your edged-weapon-based self-defense strategies around one could put you in legal hot water. As always, you must research the laws in the locations where you reside and visit. Be wary of the terms "dagger" and "dirk," as well as any language that specifies the number of sharpened edges that are permitted by law. Some laws additionally restrict the carrying of knives that are explicitly designed as weapons. Daggers are poor utility knives and are more commonly associated with weapons than general-purpose knives. When in doubt, err on the side of safety and carry a single-edged weapon.


A double-edged blade's main benefit is that it can cut in both directions that work correctly. Because of this, it can be utilized with both traditional "edge-out" and "reverse-edge" strategies without requiring you to change your grip. That implies you may combine the talents of these two knife-tactics approaches to produce a "hybrid" strategy that allows you to take advantage of targets facing both you and away from you with equal ease.

For example, an assailant swings a weapon at you with a high, forehand motion. Therefore, the interior of his arm is exposed, along with all the high-value targets it provides. The inner forearm's flexor tendons, muscles, and arteries might be targeted with outward cutting strokes with either a conventional or reverse grip. In addition, the bicep muscle, the central nerves, and the brachial artery directly below it could be targeted.

Once you've completed your cut and your knife has passed through his arm, the only thing is to aim for the triceps muscle, dragging the blade's near edge back toward you through the target. The strength of your back muscles is utilized in this powerful pulling exercise. Unfortunately, it also disables the force that allows your attacker to extend his arm and swing at you once more. Two cutting edges can be better than one, but only if used properly.

Why carry a knife in public?

Carrying a knife makes it easier to cut tape, string, clothing trailing threads, open boxes, open clamshell packaging, cut/strip wires, prepare food such as fruits and vegetables, open mail/envelopes, available food packaging, cut paper when scissors are unavailable, cut zip ties, cut tubing, remove tags from new clothing, or even for the sentiment.

In an emergency or survival situation, having a knife is extremely useful. For example, cutting seat belt straps for extrication, making cloth bandages, cutting rope, making kindling, scraping a firesteel, making a fireboard and spindle, digging out a splinter, building a shelter, preparing wild game, collecting wild edibles, making traps, carving utensils, making a spear, making an atlatl, and making feather sticks are all easier with a knife.

Is a Dagger Knife useful?

Daggers have been employed in close combat throughout human history, and numerous cultures have utilized ornamented swords in ritual and ceremonial situations. However, knife regulation in many locations bans manufacturing, sale, possession, transportation, and daggers because they are essentially weapons. Also, consider the affordable price and features of the sword or knife.


A knife is convenient in an emergency or survival situation. Whatever knife you choose, pay close attention to the edge geometry. To cut effectively, its cutting blades must be thin and sharp. Daggers provide a dilemma because double-edged blades require shorter primary bevels on each edge, unlike single-edged blades. Daggers have been used in close combat throughout human history, while many cultures have used ornate swords in ritual and ceremonial contexts.
