The buzzsaw is a tool mainly used for cutting wood. It is commonly table-mounted to reduce the danger of cutting/dismembering the user. Traditionally, it was water-powered and were too large to be used by two hands; subsequently, they were placed in saw mills. The circular wheel-blade has teeth and is made of steel. The tool is seen as a weapon in many works of fiction, including movies and video games.
