One of the most common requests we get is to look at throwing stars (Shuriken), Those are Ninja weapons of distraction, usually too light and too small to cause any serious injuries - but they are banned in Germany and many other countries anyway.
Since the German law defines a throwing star as "disk shaped", there is room for another variation: The "Death Star". It isn't a disk, but a three dimensional spiked ball.
This video shows two different sized Death Star, made from nails. They always stick in, no matter how you throw them. The bigger sized one is very heavy, therefore this video also shows you how to use a throwing stick to increase the effective distance.
