I did not initially ask WHY, did I smartass? And the question still is - WHAT good is it? WHAT is it possibly good for? WHAT use could it possibly serve in the real world? Just because something is possible does not mean it is a good idea. I can't imagine a prctical use for such a thing unless you have self-destructive tendancies. WHAT happens if the grenade jams in the fucker? You're left holding a small bomb in your hand.
