Sure, this saw is made out of Lego bricks, which are a children's toy. But it's got a real blade in there, and it really works. Yep, this is a Lego saw that could cut through a 2x4.
For safety reasons, the tips have been removed from the blade and it's set to stop if you touch it. But if they removed those safety features, this could be the most whimsical tool on any construction site.
