A kunai is a tool the ancient Ninja used to gouge holes in walls and to kill off people. Now, thanks to Tokyo-based gadget maker Solid Alliance, you can have one of these things [JP], too, if only as a USB memory stick. This is the same company that released the USB Ninja star shuriken back in May.
The new USB Kunai holds 2GB and you can get it over at Geek Stuff 4U for $125.33 plus shipping. Pay the same amount of money for the shuriken star and you’re on your way to become a true USB Ninja.
