The National
Institute of Justice, rates body armor on resistance to hand-delivered
stab threats NIJ Standard 0115.00. Slash threats have been
found much easier to defeat than stab, and thus are not specifically
addressed by this Standard.
Maximum penetration
of 0.28" / 7mm is allowed as serious injury is extremely unlikely
with such a shallow wound. Also an "Overtest" is applied,
to push the breaking point of the armor, where 0.79" / 20mm of
penetration is allowed.
Testing is done
in two different categories of threat high quality commercial
knives, called "Edged Blade" aka Stab, and ice pick, prison-style
improvised "Spike" weapons. So stab vests are rated in two
categories, "Edged Blade" or Stab and "Spike"
and can be rated for either or both categories.
The Levels were
derived from a study where several stabbing techniques of a male attacker
were tested for the force generated. In general, Level 1 is designed
to handle 85% of force levels encountered, Level 2, 90% and Level
3, 96%.

We stock our
ProMAX Concealable in Stab-Resistant and can supply most of our
ProMAX models
with the Stab-Resistant option. Or, you can upgrade your ballistic
vest with Stab Resistant Inserts.

A 'stab-proof' vest
will protect you from the vast majority of hand-delivered knife and
/ or spike threats you are ever likely to face. But there is always
a tradeoff between more protection and more wearability (and the constraint
to stay within your budget). Please know that:
- axes, hatchets,
adzes, digging picks, etc.
- claw hammers,
crowbars, etc.
- bayonets mounted
on rifles
- spears, lances,
etc.
- unusually strong
pressure or force behind the stab blow
- and/or other
unusual weapons or situations...
CAN defeat any
Stab-Resistant body armor.
Also, at some angles
weapons can slide, or deflect off the edges of Body Armor. Furthermore,
impacts that are successfully stopped by the vest will always produce
some level of injury, resulting in severe bruising, broken bones, and
possibly serious internal injury or even death. Stab-Resistant vests
defeat most common threats, but NO vest on earth makes you invulnerable.
To state the obvious, getting stabbed ALWAYS
carries some risk.
By buying a vest
you assume ALL risks of use or misuse, and agree not to hold us liable
in any way. In addition, YOU are responsible to ensure that your
ballistic and stab-resistant panels are positioned inner side IN, and
outer side OUT if applicable (check the inside vest panel labels).
