It's difficult to know what a hidden knife is if you don't know what it looks like. Whether it be a blade in the heel of a dress shoe or something more elaborate than that, this blog post will tell you everything about them. For starters, they are illegal in many areas of the world, and taking for granted that they are illegal makes owning one quite risky and nothing anyone should strive for. 

But on the flip side, some people find that owning one protects them and their family well enough so long as they keep it secret. However, even though they are illegal, you won't be able to spot one if it's in a film, TV show, or a video game. Even when knives like this aren't used as a weapon (as cool knives can be used), you can still find them in various roles as props and costumes. 

While you might not expect to see something like this in the modern day, there is still a chance that they will appear in today's media. With that all being said, here are five modern weapons that most people don't know exist in real life:

1. Brass Knuckle Knife

Brass Knuckle Knives are a type of very dangerous knife that has been banned in over a dozen countries, but they have been so popular for their use in films that they've remained present and guard many people. They aren't that hard to find, but you can read more about them by using the search bar box below. It also might seem surprising to see a fake weapon like this in today's world, but you might be shocked at how many films and TV shows use these weapons without letting anyone know what they are. 


The knives are very dangerous because they are sharp on both the inside and outside of the blade, making for a lethal weapon. The brass knuckle knife can be used for several different types of activities, but there are better choices for something. You can use it as a defensive weapon when attacked by someone with a normal knife, but you have to remember that this isn't the best option because it might hurt you just as badly as your attacker if not worse (depending on how much force is used). 

This hidden knife's true purpose is to kill or hurt an enemy who has already been stabbed or shot. Russian mafia members and drug dealers mainly use it on the streets all over the world despite being banned in many areas. This means that in most cities and countries, finding them is near impossible unless they've been smuggled into the area by accident by someone who imported them illegally.

2. Belt Buckle Knife

A belt buckle knife is a tool that has been designed to be utilized as a concealed weapon. The belt buckle knife usually features a blade of around four inches and is typically designed with an ornamental or metal-detecting design pattern. The blade may also include serrations for better cutting ability. The buckle knife is typically held by a concealed carry weapon (CCW) owner and is available to be utilized in certain situations that require the use of a concealed weapon. 


This hidden knife was first created in 1963 by a Massachusetts man named John Morris Donovan. Originally, the belt buckle knife was manufactured for personal defense purposes. It was only around thirty years ago when belt buckle knives were more widely used for offensive purposes instead of defensive ones. Today, the belt buckle knife is most commonly seen in prison-run prisons or used by clients as an alternative form of self defense weapons.

3. Pen Knife

Hidden pen knives are small, folding knives that are designed to be discreet and hidden in one's pocket. The most popular models will fit into a shirt pocket by using the button behind the handle and have a slide-action blade that opens with little or no noise. The blades can often be replaced if accidentally broken.


A hidden pen knife is not very big, which makes it easy to carry around without arousing suspicion from your boss or coworkers. It also provides more protection than a regular knife because there's less likelihood of someone getting injured since they're not swinging their weapon around wildly and exposing themselves to danger. This hidden knife is mostly used to defend yourself from an attacker since it's easy to hide and conceal. You can also use it for everyday tasks like opening mail, or using the tip of the blade for small design cuts. 

Since you're protecting yourself, you'll want to make sure that you have a good enough grip so that the knife will not slip into your hand as you're trying to defend yourself. There are some disadvantages of having a hidden pen knife besides having a garbage-quality blade. The main problem is that sometimes these knives will come with a dull blade or not be sharp at all.

4. Neck Knife

Knives are a wonderful tool, but sometimes they just don't suit your needs. When wearing jewelry leaves you vulnerable to snags or snatches, a hidden necklace knife is the perfect solution for stealthy protection. It's small enough to slip in under your shirt and out of sight. While some may think this is a high-risk approach to protecting yourself, carrying a concealed weapon is actually perfectly legal in most states.


One of the greatest advantages of owning this hidden knife necklace is that you can quickly and stealthily defend yourself, if necessary. In situations where you might need self-defense protection, it's important to remember that your primary goal is to stay safe. This could mean fleeing the scene or defending yourself once you've begun fighting back. While your options are limited in this type of attack, your hidden necklace knife can help defend against many types of attackers.

5. Boot Knife

The act of stabbing an individual with a boot knife is sometimes used in self-defense. A boot knife is also sometimes called a "stabbing knife". This hidden knife is often worn under the sole of the shoe or attached to the inside of the heel. These two locations are very inconspicuous, which can help to disarm a would-be attacker who notices it. 

Hidden boot knives are commonly found in military settings because they provide additional security for an individual while out on patrol, but it's typically against military regulations to carry them into battle. This boot knife can be made out of metal, wood, or plastic. These knives are designed to look like a normal shoe, so as not to be noticed by an unsuspecting observer. 

If you're thinking about purchasing a hidden boot knife, you should consider the fact that it will most likely get confiscated by security agents upon arrival at your destination. You could also face legal penalties if you are caught attempting to bring it onto an aircraft. If the knife is concealed under the heel of your shoe, there's a possibility that your foot could accidentally slip off the heel and send the knife flying onto the floor (it's very easy to do).

Unveiling the Stealthy World of Hidden Knives!

The topic of hidden knives presents an intriguing and sometimes contentious new angle on self-defense and covert weapons. These knives act as potential threats, as well as shields, ranging from the infamous Brass Knuckle Knife used by the shadowy figures of criminal underworlds to the understated but practical Pen Knife, meant for daily use. The Belt Buckle Hidden Knife is an example of how covert weapons have evolved; it was created out of necessity and is now accepted as a substitute self-defense tool. 

Concealed personal security is provided by the cleverly incorporated Neck Knife and Boot Knife into shoes and accessories. As we investigate these hidden blades, it becomes evident that although some are welcomed for their defensive qualities, ownership carries risks and has legal ramifications that should be carefully considered. The realm of concealed knives continues to be an enthralling and intricate terrain, connecting the dots between the need for self-defense and the eerie appeal of hidden weapons.
