The chainsaw just might be the greatest tool ever invented. Don’t believe me? Name another power tool that can be used to cut down a tree, carve a statue, and defend your family from a horde of zombies? You can’t. But is there any way to make this versatile, powerful tool even better? You could transform it into the world’s best multi-purpose tool, complete with special attachments. In a recent video, YouTuber Fireball Tool demonstrates how to make a belt sander attachment for a chainsaw.
