uPont, Wilmington, Del., has announced a new Kevlar® technology that is designed to
protect law enforcement officers, corrections officers and military personnel against multiple
weapon threats. Kevlar is a DuPont brand which is used in most bullet- and stab-resistant vests.
According to the company, this new Kevlar technology defends against threats from fire arms,
commercially manufactured knives and puncture-producing weapons such as ice picks in a concealable,
soft body armor.
The Ice Pick Test
Unlike heavier garments worn on the outside of clothing, vests using this patent-pending
technology are designed to be comfortable and flexible for everyday wear, and provides the same
level of protection across the entire vest.
According to DuPont, multi-threat body armor made with the new Kevlar provides the wearer
with ballistic protection for NIJ levels II, IIA and IIIA, and have surpassed the “California Ice
Pick Test” using a standard ice pick and a Russell boning knife.
In the ice pick test, an ice pick or boning knife is attached to a 16.2-pound weight and
dropped from a height of five feet. The energy level — measured at 81 ft.-lbs. or 110 joules — is
equal to that of a tossed javelin or a golfer driving a ball 250 yards. The knife and pick failed
to puncture the Kevlar fabric.
The fact that this fabric can stop commercially manufactured knives and puncture-type weapons is
important because these weapons are harder and sharper than hand-crafted knives, and are therefore
more dangerous to law enforcement officers on the street.
Law enforcement officers never know what kind of weapon will be used against them,” said John
Dottore, business segment leader at DuPont. “Knives and other sharp instruments are often the
weapons of first opportunity in a given situation, such as a domestic dispute or crimes of passion.
“Under certain circumstances, such as courtroom security or prisoner transfer in a
corrections or jail facility, a perpetrator may favor a knife of puncture-type instrument because
it can be easily concealed and used surreptitiously. And there is always the ballistic threat. That
is why a multi-threat vest is the best protection for specific assignments in law enforcement and
The force of 110 joules bends the blade of a Russell boning knife during the California Ice
Pick Test, but fails to pierce the multi-threat body.
Taking It To The Streets
The International Association of Chiefs of Police (IACP) and DuPont recently formed the Kevlar
Survivors’ Club® to recognize and honor law enforcement and corrections officers who have survived
potentially fatal/disabling injuries by wearing personal protective body armor. The partnership
reported more than 2,300 documented cases where law enforcement officers were saved by their body
The partnership is dedicated to reducing death and disability by having all law enforcement
professionals wear body armor 100 percent of the time while on duty. Membership is open to any law
enforcement or corrections officer who has survived a potentially life- or disability-threatening
incident by wearing body armor. Officers are nominated by their chief, sheriff, warden or
