A 1967 Speed Snips electric Scissors.
When I first plugged it in, it only growled, but oiling the hinge and spring on the blades brought them snapping to life. They worked ok for cutting paper, I haven’t tried them cloth. Since the blades are so short, they need to be advanced somewhat slowly, so I’m not totally convinced they actually save that much time over a longer length “manual” scissors. But they do save some effort if accuracy is not paramount. It is surprisingly heavy.
