How to make a real Ninja throwing star out of a saw blade with Basic tools
These Ninja stars are very easy and cheap to make with mainly an angle grinder. The big throwing star was made out of a 14 inch saw blade that was a 1/8 inch thick. The other Ninja stars were made out of old 10 inch saw blades that I had lying around.
The whole project from start to finish to make a set of 5 ninja stars and a giant ninja throwing star took about 3 to 4 hours.
This is a great Do it yourself project that will have all your friends outside acting like Ninjas throwing your new stars.
