6 Best Hidden Knives for Self Defense

Hidden knives, a.k.a. Covert weapons are usually disguised as something that could be considered innocuous such as a household item or an unsuspecting animal like a teddy bear. These deceptive items can be used for self-defense against an attacker and to escape from your home if you’re being held hostage in the event of an intruder or home invasion. 

These cool knives, however, are not all that uncommon. In fact, there are many different forms of concealed knives that vary in size and style. Also, some people use a concealed knife as an everyday household item where the blade length is the entire length of the tool and the handle is nothing more than a small swivel or lever.

Types of Hidden Blade Knives

These hidden blade knives are very controversial items that can be used for both good and bad purposes. The most commonly used knives are lipstick knives. pen knives and boot knives. While many people think that these types of knives are illegal, they're not listed under America's list of prohibited weapons. 

If a knife is considered concealed and it meets certain criteria then it can be allowed to be bought at various stores. Some of the more popular places to find these types of knives are online or in a knife store. When buying one you should choose one that isn't higher than 3 inches blade length and has a locking mechanism to prevent accidental opening.

Here are 6 most popular hidden knives for you to defend yourself in problem or emergency situation:

1. Pen Knife

A pen knife is a multi-tool which has been designed to be carried in a pocket or briefcase and which can be used as a utility knife, screwdriver, bottle opener, etc. They typically have four main components: the blade; the body of the tool; one or more blades that can fold away into the body of the tool; and sometimes additional tools (such as tweezers) designed to fit with this design.

The first pen knives were made in 1837 by Christian Frederick Faber for use by hunters, who needed hunting implements that could also serve other purposes such as cutting game straps and lacing their boots. Examples from these early days are extremely rare today due to their handmade construction methods.

2. Lipstick Knife

Lipstick knives, also called concealed knives, are ceremonial tools used in the Indonesian archipelago. They are typically small, lightweight, fast-moving blades with a single cutting edge. You can often find them adorned with traditional flower carvings and designs.

The origin of a lipstick knife dates back to ancient Indonesia which is currently home to more than 300 ethnic groups—one of which is the Dayak tribe who used these weapons for both self-defense and as a symbol of power for their chieftains.

3. Boot Knife

A boot knife is a small folding knife that can be carried in your pocket or attached to the bottom of your boots. Some are designed with a simple spring-loaded hinge that makes it easy to open and close, while others have a blade hidden inside the hinge.

These hidden blade knives are used by hikers, campers, hunters, and military personnel who need a small blade they can access quickly without sacrificing their safety. Boot knives can also be used as defensive weapons when needed - especially if you've lost your primary means of protection.

4. Necklace Knife

A knife necklace is a decorative keychain with a spring-loaded blade that can break out from the center of its body. The knife itself may or may not be as sharp as one might want, but sometimes it has less than lethal blades such as nail file and tweezers on the handle.

Pros and Cons of Self Defense Hidden Knives

  • Pros

You will probably be able to conceal or hide your knife(s) in various places in order to surprise an attacker with deadly force. It’s important to remember that deadly force is only warranted in response to deadly force. For example, if someone was holding a knife to your throat or using their hands or feet to inflict bodily harm, you would have the legal and moral justification to respond with deadly force.

  • Cons 

You should always remember that knives are close-range defensive weapons. They should never be used as an offensive weapon. Regardless of how much you know about martial arts or how proficient you are in the use of a concealed knife, it will probably be used against you by a more experienced and better trained opponent.
