Yep.. an electric "Lids Off" jar opener. It's advertised as a gizmo for motion restricted people, but it's designed by Black and Decker. As much as I love gadgets ....
An antique store, on upper Grant, has something similar. It's mechanical, with a sort of ecentric geared arrangement to spin the jar, while the top is trapped in a knurled V. Sixty years later, it still works fine. Draw your own conclusions.
