This chainsaw made out of Lego blocks doesn't actually cut things, unfortunately. (It's probably for the best but, you know, that would be awesome.) But it does operate in every other way, with a motor, brake, spinning band, handle, etc. So, theoretically, if you wanted to make one of these with real sharpened teeth, it would be possible. Not that we're saying that's a good idea, mind you. Just that cutting down a (probably small) tree with Legos would be pretty awesome.
