Who done it? The perfect weapon for the assassin who wants to remain at the party and watch his victim choke to death from poison and no one have a clue who the killer is. Another murder mystery. The artwork above is Stock - Poison bottle by the talented Deviant art artist rockgem
#4 Predator drone
The US has already used this unmanned war plane to kill many suspected prominent al Qaeda members without puting a single soldier in harms way.

Perhaps it would take the most balls to walk up and stab your victim to death with a knife
#7 Rocket launcher
Made famous by Brigette Mohnhaupt (below) in her battle against Capatilism
Preferred weapon of the ninja assassin the mighty sword slays many victims up close and personal. (Above) A screen shot from the popular movie Ninja Assassin

Not the most effective tool of the assassin but ancient Japanese killers felt it brought honor to a dark profession
