A personal tragedy turned into a business for this Iowa man.

Anyone who uses body armor puts stock (and faith) in it, that it will work when it needs to. Our service men and women also arm themselves with these protective devices, trusting it will save their lives.

A former marine and police officer Blake Waldrop of Iowa, set out to make the world's safest body armor after losing his best friend in 2005 during an IED attack in Iraq, according to DesMoinesRegister.com.

There are all kinds of designs out there made from other companies, but Waldrop aims to make this the very best in the world for protection.  He testing includes six rounds of rifle ammo, something he says can't be matched by competitors.

The demand for what Waldrop sells increased after the high profile police shootings in Des Moines last November.
