Have you ever fantasized about shooting someone in the neck with a poisoned dart, then sneaking up behind them and cutting their throat with a 3.5" blade? If you have, you should never tell anyone because it will make people uncomfortable and/or afraid.
This bizarre ninja assasination kit comes with the knife, 2 pieces of rubber tubing which assemble into your blow gun, and 3 darts. No poison, but a fancy pouch for easy concealment, which you will need because there is nothing that you can do with this that won't involve scaring someone badly enough to call the police.
$14.94 at Swords, Knives, and Daggers.
