What does this device accomplish in the kitchen, besides being able to make fine slices of vegetables more easily? Electric carver knives beat it for slicing meat.

And then for most any other situation of knife usage it isn't necessary at all, as knives are mostly used for chopping. The one (1) thing I can see this being useful for is a shrunken down version for paring, but whether or not that is mechanically feasible, I don't know. The curve and the handle are more important than this vibro-verbing.

Nice dialogue, btw. "Help chefs feel great about themselves in the kitchen", "access to sous vide". <Kitchen Woke> ?
