"Claw machine" mixer
I saw a video of a mixer that reminded me of the claw machine in a game arcades, except it had only two claws instead of four. Of course, now I can't find the video and can only describe its motion. The claws open, it drops to bottom of the bowl, then grabs and lifts the dough.
I've never seen this kind of action on a food mixer, but I supposed it is designed for a particular end product. How are the results different from using a KitchenAid or a "cement-mixer" type?
