A Chainsaw is a mechanical saw that travels on wires in the game Super Mario World. Mario can perform a Spin Jump or stomp it while on Yoshi to rebound on these objects.
They appear in most of the levels that have wires with platforms traveling across them. A huge group is on the Twin Bridges, and some have ropes dangling under them. Climb the ropes and try to avoid the other Chainsaws, or things could get very messy.
