"Some body armors are made to be stab (edged blade and/or spike) resistant, and other body armor that is made to be bullet proof.
If a vest features stab protection, it is not necessarily bullet proof. Equally, a bullet proof vest may offer no protection to bladed weapons. Also, a vest which is bullet and edged blade resistant may offer no protection to spike threats (i.e. screwdrivers, knitting needles, syringes etc.)"
