What is Stab Resistant Armor?

Stab-resistant armor is designed specifically to shield the wearer from assaults using pointed implements such as knives, needles, and spikes. Similar to bulletproof vests, stab-resistant vests are engineered to prevent penetration by sharp objects, utilizing a tighter weave to impede smaller items from breaking through.

Materials used in both stab and spike-resistant armor typically comprise high-strength synthetic fibers such as Kevlar or Spectra, along with laminated elements. The weave employed in these materials is generally denser than that found in bullet-resistant vests, often incorporating a laminate layer to enhance the protective capabilities of the complex fiber network.

What is Edge Blade Resistant Armor?

Edge blade-resistant armor is crafted to defend against assaults from instruments equipped with cutting edges, including knives and machetes. The primary objective of this armor is to thwart the slicing actions of such weapons capable of severing fabric and inflicting life-threatening wounds.

The construction technique for edge blade-resistant armor generally includes multiple layers of cut-resistant materials such as aramid fibers (e.g., Kevlar), ultra-high molecular weight polyethylene (like Dyneema or Spectra), and occasionally metal or ceramic elements. The intention is to establish a barrier that the edge of a blade cannot easily penetrate.

What is Multi-Threat Armor?

Multi-threat armor is designed for protection against an array of assaults encompassing a mixture of ballistic threats, edged blades, spikes, and blunt force trauma. This form of armor is often preferred by law enforcement personnel.

Multi-threat armor's construction changes according to the threats it aims to counter. It typically combines various materials and technologies utilized in stab-resistant, spike-resistant, edge blade-resistant, and bullet-resistant armor.

Common Armor Materials

Body armor is required to be both resilient and flexible, capable of enduring substantial force while enabling the wearer's mobility. High-strength synthetic fibers like Kevlar, Dyneema, or Spectra are regularly used. These materials exhibit high tensile strength and are woven into a dense, pliable fabric. Additional layers of laminated materials and composites are sometimes integrated for enhanced safeguarding.

Threat Levels & Protection

The National Institute of Justice (NIJ) is responsible for establishing performance standards for stab-resistant armor and body armor. The NIJ's threat levels are intended to assist users in evaluating the protective capabilities of various body armor types.

NIJ body armor levels:

• Level IIA: Protects against 9mm and .40 S&W.
• Level II: Protects against .357 Magnum jacketed soft point (JSP) bullets.
• Level IIIA: Shields against .357 SIG FMJ flat nose bullets and .44 Magnum semi-jacketed hollow point (SJHP) bullets, alongside threats addressed in Levels IIA and II.
• Level III: Protects against 7.62mm FMJ jacketed bullets (U.S. Military designation M80), encompassing threats mentioned in Levels IIA, II, and IIIA.
• Level IV: Provides defense against .30 caliber armor-piercing bullets (U.S. Military designation M2 AP) and threats delineated in Levels IIA, II, IIIA, and III.

Concerning stab resistance, the NIJ specifies three levels related to .00 protocols:

Level E1

Level E2

Level E3

Understanding these classifications requires comprehension of how the NIJ defines threats posed by stabbing and edge attacks at these levels. They categorize weapons as a commercial class (termed “The streets” class), representing what officers might face routinely, such as commercially produced knives or swords. The second class acknowledges improvised weapons found in correctional facilities, including shives and picks.

These two weapon classes are then compared to a standard criterion reflecting the 1-100 percentile capability of adult males to breach the armor using these weapons from multiple angles. Level E1 signifies the 85th percentile, indicating that only the strongest 15 out of 100 males could breach the vest with various types of attacks. E2 corresponds to the 90th percentile, while E3 denotes the 96th percentile, meaning only 4% of the strongest males could penetrate the vest.

Soft Armor Advantages and Disadvantages

Soft armor is lightweight and flexible, providing a comfortable wear experience. It's typically affordable and can be discreetly worn under clothing. However, it does not deliver the same level of protection from specific threats, such as rifle bullets, as hard armor does.

Advantages and Disadvantages of Stab Proof Vests

Stab proof vests are intended for protection against edged weapons, such as knives. These vests are generally lightweight, permitting comfortable wear over extended periods. Nonetheless, they may not offer sufficient defense against ballistic threats unless explicitly designed for such.

Advantages and Disadvantages of Spike Proof Vests

Spike proof vests protect against improvised weapons like ice picks, shanks, and knives, making them vital for individuals facing such threats. However, akin to stab proof vests, they might not sufficiently guard against ballistic threats unless specifically engineered for those situations.

Advantages and Disadvantages of Edge Blade Vests

Edge blade vests aim to shield against cutting-edge weapons such as knives or machetes, significantly lowering the risk of lethal injuries. However, they may offer reduced effectiveness against blunt force trauma, ballistic threats, or pointed instruments.

Advantages and Disadvantages of Multi-Threat Vests

Multi-threat vests provide protection against a wide range of threats, increasing their versatility across various scenarios. However, they can be bulkier and pricier than other vest categories due to the additional layers of protection.

Soft Armor vs. Hard Armor

Soft armor, crafted from woven or laminated fibers like Kevlar and UHMWPE, presents a lightweight and flexible option, ideal for daily wear. It aims to trap and decelerate projectiles or mitigate blunt force impact. However, soft armor cannot stop rifle rounds.

In contrast, hard armor is typically constructed from materials such as ceramics, steel, or polyethylene, affording robust protection against rifles. This type of armor can withstand rifle bullets and provides added safety against sharp objects. Hard armor, however, often entails greater weight and less comfort for prolonged wear.

Stabproof vs. Bulletproof

Stab proof vests are designed to thwart penetration from sharp objects like knives or broken bottles. Bulletproof (or bullet resistant) vests are formulated to dissipate the impact energy of a bullet, impeding its entry through the vest.

It's crucial to acknowledge that while some vests could offer both bullet and stab protection, those specifically engineered for one may not necessarily shield against the other.

The terminology often confuses many as we commonly hear the term "bulletproof vest." However, "bullet resistant" is a more accurate phrasing, as no armor can be deemed completely bulletproof. This fact underlines the necessity for the NIJ to assign varying armor levels to clarify threats that each type can withstand.

Civilian Use of Stab Proof Vests

Stab proof vests can serve as a beneficial safety measure for civilians in specific professions or situations where there exists a risk of attacks from edged instruments. For instance, law enforcement officers, security staff, delivery personnel, or individuals working in high-crime regions may opt for a stab proof vest to enhance personal protection.

If you are a soldier, law enforcement agent, security guard, or just someone who feels that they need to improve their protection, a Kevlar® vest may be the optimal choice for you. Body armor made from Kevlar protects against ballistic (bullet) threats, and additional layers can expand to include even certain rifle rounds. Vests made from this material are lightweight, dependable, and durable, making them an ideal choice in different environments and scenarios. Compared to other materials on the market, Kevlar body armor outperforms them in terms of flexibility and high protection-to-weight ratio.

Lighter Body Armor: Kevlar

Historically, bulletproof panels have always been heavy. This is due to the heavy materials used. Vests often used steel plates as protective panels, which is not the ideal material. Eventually, scientists and developers started collaborating to find an alternative that would give people the protection they needed while keeping mobility high and the weight low.

After several years of research, a breakthrough occurred in the 1960s when Kevlar was discovered by the DuPont Company. Originally used in the manufacture of racing tires, developers realized that its durability and low weight made it ideal for other purposes. After additional developments and tests, Kevlar proved to be much stronger than steel, at just a fraction of its weight. Scientists then focused on designing this material in a way that allows it to be used in ballistic panels for body armor protection. After many years of development, they achieved this, and today, Kevlar remains one of the best materials in the manufacture of protective equipment.

Kevlar offers exceptional protection against ballistic/bullet threats. For people working as security guards or law enforcement officers, covert vests made of this material provide an excellent level of protection. Kevlar is lightweight, flexible, and relatively thin, which allows it to be easily worn under clothing and remain concealed. It is also used in the manufacturing of overt vests, which are worn by military operatives with additional panels and plates for more protection from heavy enemy fire.

Kevlar panels are available in different protection levels, allowing wearers to select the level that meets their needs. For example, a security guard will likely not require the same protection as a military operative in a war zone.

For Kevlar vests to remain as effective as possible, they need to be properly stored and handled, which includes keeping them away from water and direct sunlight. Specially designed carriers for storage are an option if you want to be sure that your vest does not get creased or bent as this can compromise its integrity. Hanging the vest is not recommended as it puts strain on the fibers. Storing it in a flat position on a shelf is acceptable only when it is not pressed against other pieces of clothing or items.

These precautions ensure that the body armor will retain its protective properties and continue to serve its purpose for many years. The Kevlar material has a long shelf life and can remain viable for a very long time if you take proper care of it.
