Making Simple Throwing Spikes - Ninja Bo Shuriken

Making some simple throwing spikes also known as Bo Shuriken. They are made from 1/4 inch masonry bits. The tails of these bits are quite hard as they are designed to be hit by the drill so they will make good points. I opted for 6 mm bits so that the head is heavier, making them more stable in flight. They were also very cheap, paid under a buck each. ----------------------- WARNING: These are not toys and are very dangerous!
