One of Batman‘s coolest tools is his bat-shaped stars known as the Batarang. Every nerd wishes they could wield the sweet bat-stars, but where can one acquire an authentic Batarang? They aren’t really easy to come by. Super how-to nerd Grant Thompson had an old table-saw blade that he was replacing, and realized its superhero potential. With a little hard work, he was able to create five super sweet Batarangs, each with a different Batman design. Awesome.
