A stab vest or stab proof vest is a reinforced piece of body armor, worn under or over other items of clothing, which is designed to resist knife attacks to the chest, back and sides.
Stab vests are different from bulletproof vests, which offer protection against firearms but are ineffective against stabbing attacks. They are constructed using high-strength synthetic fibers with a tighter weave than bulletproof vests and can be reinforced with other laminates. [1] [2] [3]
Stab proof vests are standard issue to police officers in both the United Kingdom and New Zealand. [4] They are also commonly worn by paramedics, security staff, traffic wardens, environmental wardens, customs officers, immigration officers, bailiffs, cash in transit officers, door supervisors/bouncers, or anyone who else may be under threat.[ citation needed ]
Bulletproof vests are more commonly used by police in countries with greater firearms ownership, such as the United States and Canada; but dual-purpose armor plates that protect against both stab and firearms attacks are fairly widely available for police and also security applications.[ citation needed ]
In the mid-1980s the state of California Department of Corrections issued a requirement for a body armor using a commercial ice pick as the test penetrator. The test method attempted to simulate the capacity of a human attacker to deliver impact energy with their upper body. As was later shown, this test overstated the capacity of human attackers. The test used a drop mass or sabot that carried the ice pick. Using gravitational force, the height of the drop mass above the vest was proportional to the impact energy. This test specified 109 joules (81 ft·lbf) of energy and a 7.3 kg (16 lb) drop mass with a drop height of 153 cm (60 in) and an ice pick with a 4 mm (0.16 in) diameter with a sharp tip with a 5.4 m/s (18 ft/s) terminal velocity in the test. The California standard did not include knife or cutting edge weapons in the test protocol. In this early phase only titanium and steel plate offerings were successful in addressing this requirement.
These textile materials do not have equal performance with cutting-edge threats and these certifications were only with ice picks and were not tested with knives.
The Police Scientific Development Branch (PSDB) work studied the type of weapons that are commonly used in stabbing attacks and the levels of impact energy fit young men are capable of generating during such an attack. The study resulted in minimum performance ratings for armour used in the UK, as defined under PSDB publication 6/99. The PSDB standard was replaced in 2007 with the current Home Office Scientific Development Branch (HOSDB) publication No. 39/07/C which governs stab resistant body armor performance in the UK. This updated standard introduced a more stringent testing procedure with more drops than the previous standard plus the introduction of the P1/B Blade which is found to be more aggressive that the older P1/A Blade. [5]
In the UK there are no standalone ratings for spike resistance. For stab resistant armor to carry a spike resistance (SP) rating in the UK, it must first pass minimum knife resistance (KR) performance tests.
In the US, the National Institute of Justice (NIJ) has established a stab-resistant body armor test standard (NIJ STD 0115.00), [6] based on the work in the UK, which defines two threat types: spike and edged blade.
Manufacturers of body armor can voluntarily submit armor models for compliance testing through the National Law Enforcement and Corrections Technology Center in Rockville, Maryland. Through the program, manufacturers certify that their armor will defeat the specified threat at one of three threat levels. Threat levels 1, 2 and 3 are based on impact energies of 24 J (18 ft⋅lbf), 33 J (24 ft⋅lbf), and 43 J (32 ft⋅lbf) joules respectively.
A bulletproof vest, also known as a ballistic vest or bullet-resistant vest, is a type of body armour designed to absorb impact and prevent the penetration of firearm projectiles and explosion fragments to the torso. The vest can be either soft—as worn by police officers, security personnel, prison guards, and occasionally private citizens to protect against stabbing attacks or light projectiles—or hard, incorporating metallic or para-aramid components. Soldiers and police tactical units typically wear hard armour, either alone or combined with soft armour, to protect against rifle ammunition or fragmentation. Additional protection includes trauma plates for blunt force and ceramic inserts for high-caliber rounds. Bulletproof vests have evolved over centuries, from early designs like those made for knights and military leaders to modern-day versions. Early ballistic protection used materials like cotton and silk, while contemporary vests employ advanced fibers and ceramic plates. Ongoing research focuses on improving materials and effectiveness against emerging threats.
Personnel Armor System for Ground Troops is a combat helmet and ballistic vest that was used by the United States military from the early 1980s until the early or mid-2000s, when the helmet and vest were succeeded by the Lightweight Helmet (LWH), Modular Integrated Communications Helmet (MICH), and Interceptor body armor (IBA) respectively.
The 7.62×25mm Tokarev cartridge is a Soviet rimless bottleneck pistol cartridge widely used in former Soviet states and in China, among other countries. The cartridge has since been replaced in most capacities by the 9×18mm Makarov in Russian service.
A flak jacket or flak vest is a form of body armor. A flak jacket is designed to provide protection from case fragments ("frag") from high explosive weaponry, such as anti-aircraft artillery, grenade fragments, very small pellets used in shotguns such as the "Birdshot", and other lower-velocity projectiles. It is not designed to protect against bullets fired from most small arms such as rifles or handguns. However flak jackets are able to sustain certain gunshots, depending on the angle at which the shot was fired, the caliber of the bullet, the speed of the projectile and the range from which the shot was fired.
Body armor, personal armor, armored suit (armoured) or coat of armor, among others, is armor for a person's body: protective clothing or close-fitting hands-free shields designed to absorb or deflect physical attacks. Historically used to protect military personnel, today it is also used by various types of police, private security guards, or bodyguards, and occasionally ordinary citizens. Today there are two main types: regular non-plated body armor for moderate to substantial protection, and hard-plate reinforced body armor for maximum protection, such as used by combatants.
Bulletproofing is the process of making an object capable of stopping a bullet or similar high velocity projectiles. The term bullet resistance is often preferred because few, if any, practical materials provide complete protection against all types of bullets, or multiple hits in the same location, or simply sufficient kinetic (movement) energy to overcome it.
The Small Arms Protective Insert (SAPI) is a ceramic ballistic plate used by the United States Armed Forces. It was first used in the Ranger Body Armor and Interceptor Body Armor, both are ballistic vests. It is now also used in the Improved Outer Tactical Vest as well as the Modular Tactical Vest, in addition to commercially available "plate carriers". The Kevlar Interceptor vest itself is designed to stop projectiles up to and including 9×19mm Parabellum submachine gun rounds, in addition to fragmentation. To protect against higher-velocity rifle rounds, SAPI plates are needed.
A ballistic plate, also known as an armour plate, is a protective armoured plate inserted into a carrier or bulletproof vest, that can be used stand-alone, or in conjunction with other armour. "Hard armour" usually denotes armour that uses ballistic plates.
Second Chance is an American body armor manufacturing company. The company was founded in the early 1970s by U.S. Marine and pizza delivery owner/driver Richard Davis. Davis developed the idea of a bulletproof vest after shooting three armed robbers in self-defense during a delivery. This incident was later documented in a 1995 book written by firearms instructor Massad Ayoob called The Ayoob Files: The Book.

Notable clients include King Felipe VI of Spain, Michael Bloomberg, former Colombian president Álvaro Uribe, former Venezuelan President Hugo Chávez, former U.S. President Barack Obama, and former Mexican President Enrique Peña Nieto.
The Improved Outer Tactical Vest (IOTV) is an enhanced version of, and a replacement for, the older Outer Tactical Vest (OTV) component of the Interceptor multi-threat body armor system, as fielded by the United States Army beginning in the mid-2000s. The IOTV is compatible with the Deltoid and Axillary Protector System (DAPS) components, ESAPI, Enhanced Side Ballistic Inserts (ESBI), as well as the OTV's groin protector. A flame-resistant standalone shirt, the Army Combat Shirt (ACS), was designed in the late 2000s specifically for use with the IOTV.
Dragon Skin is a type of ballistic vest first-produced by the now-defunct company Pinnacle Armor, and was subsequently manufactured by North American Development Group LLC. The vest manufacturer claimed that it could absorb a high number of bullets because of its unique design involving circular discs that overlapped, similar to scale armor.
Liquid armour is a material under research by defense institutions and universities around the world including the United States Army Research Laboratory (ARL). Some of the earliest research in this area was performed at Massachusetts Institute of Technology and University of Delaware in 2003. Liquid armor was initially presented as a way to increase the survivability of soldiers in high risk roles while retaining their mobility, as reported by NPR in an interview with MIT professors and a U.S. admiral.
The use of personal protective equipment (PPE) is inherent in the theory of universal precaution, which requires specialized clothing or equipment for the protection of individuals from hazard. The term is defined by the Occupational Safety and Health Administration (OSHA), which is responsible for PPE regulation, as the "equipment that protects employees from serious injury or illness resulting from contact with chemical, radiological, physical, electrical, mechanical, or other hazards." While there are common forms of PPEs such as gloves, eye shields, and respirators, the standard set in the OSHA definition indicates a wide coverage. This means that PPE involves a sizable range of equipment. There are several ways to classify them such as how gears could be physiological or environmental. The following list, however, sorts personal protective equipment according to function and body area.
