That could be handy.
Thats actually a neat idea but I couldn't inmagine what it would be used for.
I could imagine using it in a [Medieval?] RolePlay;
"Ah, it's good to be back from fighting those trolls, best put my bloodied mace away, don't wish to lose it in some unforseen accident" *Throws Mace onto holding brick* "There,that should do, now to light the fireplace"
*Moves over to fireplace, lights wood, BOOM! Sudden explosion from wood, player is killed*
2 mins later
"Darn death, good to be back home, again. Hey! My Mace, its still there, atleast i can kill some more Trolls!"
And so, life goes on.... :D
