These days it’s hard for Ninja’s. First there’s extra security everywhere. Second, there are so many weapon choices available. How do you decide? Do you go with Wolverine claws? Or bust someone’s face with an umbrella? There’s always Dark Knight throwing knives.

Here’s another more practical option for the modern ninja. It’s a blowgun that doubles as a 3.5-inch knife. You can get yours, along with a “go straight to jail” card, for just $20. It pays for itself after your first kill.
