Can stab-proof clothing really prevent stabbing?

Stab-proof clothing is also called anti-knife clothing, anti-blade clothing or anti-blade clothing. It has functions such as anti-knife cutting, anti-knife slashing, anti-knife stabbing, anti-scratch with angular objects, anti-wear, and anti-theft. Stab-proof clothing follows the GA68-2008 "Stab-proof clothing" standard. The relevant requirements of this standard are: protection level 24 joules kinetic energy, no tip exposed; surface density of stab-proof material: < 10 kg/m2; protection area and weight: 2.8kg.
Stab-proof clothing is often divided into hard stab-proof clothing and soft stab-proof clothing according to the material of the stab-proof liner. The stab-proof liner of the hard anti-stab suit is made up of more than 50 pieces of tungsten steel sheets stacked in a fish-scale arrangement. When encountering a knife stab, the tungsten steel sheets can better protect the person's chest and back. The stab-proof liner of the soft stab-proof clothing is made of multiple layers of stab-proof PE cotton felt, which is generally divided into 16 layers, 20 layers or more layers of stab-proof PE cotton felt.
According to the ministerial product standards, the protection level of the stab-proof clothing is 24 joules of kinetic energy. We stabbed the knife hard into the liner of the stab-proof clothing, and the stab-proof clothing was not punctured. To sum up, wearing stab-proof clothing can really achieve the effect of stab-proof.
