What armor is best against stabbing?

Will a bulletproof vest stop a knife? 

While bulletproof vests are designed to protect against bullets, many wonder, can a knife go through a bulletproof vest? The short answer is, yes, but the long answer requires an awareness of a few important factors.

It is important to understand that the requirements for knife and ballistic protection vary. A high rating in one field does not ensure a corresponding high rating in the other. While all of Premier Body Armor's products have a natural knife resistance, they are not specifically designed for protection against stab or slash attacks. 

You can learn more about body armor ratings for ballistic threats in our article, and learn more about stab rating NIJ standards.

What is a spike rating?

Spike rating is a metric developed by the National Institute of Justice (NIJ) that measures the stab resistance of armor. A level 1 spike rating indicates that the armor will protect against attacks with a force of 17.7 foot-pounds or less. Level 2 protects against attacks of 24.3 foot-pounds or less, and level 3 protects against attacks up to 31.7 foot-pounds in strength. A foot-pound is the amount of energy required to move 1 pound a distance of 1 foot.

The NIJ also provides an 'edged blade' resistance chart, that indicates body armor with a level 1 spike rating also protects against slash threats of the same intensity. 

What to consider for body armor knife protection: 

When looking for the right body armor for knife protection, you should look for armor that offers slash protection as well as stab resistance. This will provide protection against both types of attacks.

Furthermore, consider the material that the ballistic armor is made from. Kevlar and polyethylene are the two most common materials used to make armor to protect against knife attacks. Ceramic and steel can also provide some level of protection. These products will often carry a 'stab resistant' or 'slash proof' designation. 

However, it's important to note that no body armor is completely stab proof. Even the most effective armor can be penetrated by a determined attacker. That being said, body armor can still provide a significant level of protection and can reduce the risk of serious injury or death in the event of a knife attack.

What types of body armor will also stop a knife?

Nowadays, most ballistic armor will provide some level of resistance against stab and slash risks, as modern manufacturing techniques and materials such as Kevlar, polyethylene, ceramic, and steel ensure armor that is durable enough to defend against both ballistic and knife threats.

Will a plate carrier stop a knife? Yes, a fully loaded plate carrier will provide some protection against a knife threat, as long as the strike lands on either a front or rear plate. 

Kevlar body armor and edged weapon protection:

Kevlar is a synthetic fiber commonly used in body armor manufacturing due to its strength and durability. It can provide great protection against knife threats as the tightly woven fibers are difficult to puncture and can deflect slashing attacks as well. Many soft ballistic protection vests are made of Kevlar due to all around utility and the lightweight construction.

Polyethylene body armor and knife stabbing protection: 

Polyethylene body armor is another popular choice for both ballistic and knife protection. Due to the high molecular density, polyethylene provides excellent protection against stab attacks while maintaining strength and durability. Polyethylene is preferred by many because it is lightweight compared to its other rigid material counterparts. 

Ceramic body armor and knife stabbing protection: 

Ceramic body armor is another choice that will provide protection against knife threats. This is in part due to the rigidness of the material. Ceramic armor plates are often combined with another form of armor, typically Kevlar, to provide more protection while still keeping weight down. 

Steel body armor and knife stabbing protection:

Steel armor plates are capable of providing protection against knife threats, but are typically reserved for cases where ballistic threats are the most prevalent, as steel armor can be heavier than its alternatives. Steel armor might be preferred in stationary situations where mobility is not as important to the user. 

How effective is a stab proof vest?

Stab proof vests are highly effective at stopping knife threats, as they have been specially designed to do so, whether through choice of materials or a tightly woven construction method.   

How many stabs can a bulletproof vest take?

When it comes to effectiveness, the number of stabs a bulletproof vest can take depends on the material and design of the vest. While some vests may be able to withstand multiple stabs, others may only be effective against one or two attacks. 

It's also worth noting that repeated stabbings in the same area can weaken the protection provided by the ballistic armor, so it's important to replace the vest after any such attack.

Do different body armor ratings have better stab resistance?

Finally, it's worth considering whether different ballistic armor ratings offer better stab resistance. While there is no one-size-fits-all answer to this question, higher-rated ballistic armor is generally more effective at stopping knife attacks than lower-rated armor. The NIJ provides a range of ratings for body armor, and it's worth considering these when choosing armor for knife protection.

When choosing body armor for knife protection, it's important to consider the level of protection provided, the material used, and the body armor rating. Ultimately, while no body armor is completely stab proof, wearing any armor significantly reduces the risk of serious injury or death in the event of a knife attack.

Are you looking for the best stab-proof vest?

In the United States, death by knife attacks is the next most common cause of homicide after firearms.

When entering a home for a domestic situation, there are two locations law enforcement officers keep everyone away from: the master bedroom and the kitchen.

Knife wounds are no joke and even for law enforcement there is almost no avoiding getting stabbed or cut during a knife attack.

Whether you're a journalist, military, private security, or law enforcement, the right stab-proof vest could be the difference between some bandage and a stay in intensive care.

Keep reading and discover our top recommendations for stab-proof vests.

What is a Stab Proof Vest?

Stab-proof vests or stab vests are pieces of body armor that can be worn under or over clothing, designed to resist knife attacks to the chest, back, and sides.

A stab vest differs from a bulletproof vest in how it handles the impact of the object. Bulletproof vests displace and absorb the energy generated by the projectile at the point of impact. However, this does nothing for an edged weapon that can cut through the fabric.

Stab-proof vests work by creating friction between the edged weapon and the material of the vest. The thickness of the material used absorbs and displaces the energy at the impact point across the chest. The tightly woven mesh creates friction and slows the weapon eventually trapping it in the material.

It's important to note that stab protection does not offer protection against sharp-tipped objects or blunt objects such as needles or baseball bats. Stab-resistant vests are meant for sharp-edged weapons and bladed weapons such as knives and swords.

Currently on sale for $233.99, this stab-resistant armor may be extremely lightweight but can offer protection from edged weapons and blunt trauma. Rated KR1 by CAST, this stab-resistant vest can withstand 24 joules of impact force from edged weapons.

Stab-Proof Vest Rating Standards

The United States Institute of Justice (NIJ) has established standards for stab-proof vests according to their ability to resist knife attacks of different force levels.

Protection Standards of Stab Resistant Vests

The NIJ rates stab vests standards using levels 1 through 3 and can effectively withstand attacks ranging from 24 to 43 joules of force.

NIJ Standards

The NIJ rates stab vests standards using levels 1 through 3 and can effectively withstand attacks ranging from 24 to 43 joules of force.

CAST Standards

The CAST standards use 2 levels of ratings for body armor and compares resistance to a percentage of real-life knife attacks.

• Level 1 (KR1) can withstand the same amount of force used in 85% of real-life knife attacks.
• Level 2 (KR2) can withstand the same amount of energy and force used in 90% of real-life knife attacks.

For KR1 stab vests, the wearer can expect to be protected against 24 joules of strike energy.

NIJ and CAST Ratings and You

These standards ensure that stab-proof vests used will protect the wearer from the threats it claims to. Purchasing a vest not rated by the NIJ or (CAST) is too risky a venture.

As a real-world comparison, 24 joules of force is roughly equivalent to being hit by a baseball traveling at about 10 mph. It's slightly weaker than an average man's punch, but focused into the area of a knife's edge, making it far more dangerous than it sounds.

For most people, a Level 1 degree of protection is sufficient enough to protect against most stabbing attacks.

The Best Stab-Proof Vest for You
