Working LEGO chainsaw (massacre not included)

It may not cut through much, perhaps not even warm butter, but this gorgeous little LEGO chainsaw by František Hajdekr is one of the coolest things I have ever seen. And it really works! The Technic panels and liftarms fit together as snugly as a jigsaw puzzle. Inside you’ll find a battery box and a Power Functions motor. The safety guard also acts as a safety catch. A simple trigger controls the action. But why take my word for it? See for yourself!

Bonus: the builder has also constructed a power drill and a dune buggy, which also feature Power Functions functionality.
