It’s called chainsaw ice skating and Erik Sunnerheim is a master of it. A chainsaw smoothly chews through the ice of a frozen lake, pulling him rapidly over it.
This would make a great addition to ice hockey! Players could alternate the use of their chainsaws for propulsion and as hockey sticks. Or they could each hold a chainsaw in one hand and a hockey stick in the other. Let’s try it! Here, hold my beer.
