This is a wrench that was being carried around by a guy who gave a seminar at my work. It is a wrench created in a 3D printer, which uses some sort of fillaments to basically create anything in three dimensions the same way you can print out a document on paper. I have it on good authority that such a printer is used for prototyping.
Best part is that it has moving parts. The screw thing goes twirling around, and moves the teeth. Word!
