Lance Abernethy, a man from New Zealand made headlines a few months ago for 3D printing the world's smallest working power drill. Now he is at it again with perhaps an even more incredible creation. Abernethy has now designed and 3D printed what he considers to be the world's smallest working circular saw. Powered by a hearing aid batter, the saw turns on and operates like your traditional circular saw, although Abernethy says that he is still working to make it so that it can actually cut through objects. He plans to continue developing this further and also make even more miniature power tools in the future.
