LAKEWOOD, Colorado -- A man was charged with murder for allegedly killing his nephew while demonstrating a bulletproof vest they believed could also stop knives.

Amando Aranda, 32, was jailed without bail in the death of Gabriel Aranda, The two men shared a pint of whisky, drank beer and smoked marijuana before staging the demonstration Friday for a teenager, authorities said.

Aranda took a long kitchen knife and stabbed his nephew in the chest, penetrating his heart, police said.

"The suspect and victim were trying to demonstrate their belief that this type of protective vest could withstand a knife attack," police spokesman Steve Davis said.

"Obviously, that was incorrect."

I find myself wondering how the thought of this demostration came about.

I think it was a once in a million chance that the knife would penetrate that vest.  They should repeat the test, only this time with the other guy wearing the vest.

I read once about a college student who tried to play Russian Roullete with an automatic pistol

Beleive it or not it's easier to make a light wieght bullet proof vest than it is to make a light wieght knife proof vest; the key words being light weight.

They're very different weapons requiring different solutions.

a needle will go through a "bullet proof vest", how do you think they sew the things together?

[Nifty]

did they think they had Bilbo and Frodo's mithril vest  or something?  sheesh.

[GrimCO]

Simple solution is to wear a trauma plate. That's what they make the insert for on the front of the vest. I wore one. Knife won't go through it  :-)

Bulletproof and and stab-resistant vests are different.  Many police in the UK wear only stab-resistant vests (IIRC), while US cops usually wear bulletproofs.  I think that there may be some all-purpose vests in development that I heard about on the discovery channel or somewhere similar.  

I remember reading somewhere that the pressure exerted by a knife tip (moderate force exerted over a very small area) is much higher than the pressure exerted by a relatively flat-faced pistol round (lots of energy dissipated over a relatively large area).  This combines with a bullet's tendency to deform (diffusing energy), and a knife's tendency to remain rigid.  Thus the ability of a knife to go through the bulletproof vest.
