Chainsaws are a beloved American power tool, mostly because they let us be utterly irresponsible with something sharp attached to a motor. But some of us push the chainsaw to its very limits. Like this surprisingly precise grandpa, who wants to open his beer.

What impresses us the most is how accurate he is. You can't see it up close, but what happens is the saw is just close enough that a link in the chain hooks onto the cap and yanks it. It goes so fast that it rips the cap off, while leaving the beer bottle intact.

Our question is this: how'd he figure this out? And does he use the chainsaw anywhere else around the house? Does Thanksgiving require safety goggles?
