A saw made out of Lego bricks, but with a real blade is a hospital trip just waiting to happen. This thing really works. So I hope they’ve alerted the local ER. This Lego saw can cut through a 2×4, so limbs should be no problem.
Just to be extra safe, the tips have been removed from the blade and it’s set to stop if you touch it. But still. I don’t trust this Lego saw one bit. But it is a cool creation. I’m now looking forward to the Lego nail gun and jackhammer. Once those are ready, I can make my own Lego themed construction site where our hard hats snap onto our heads and the buildings are many colored bricks.
