Is there a fully automatic kitchen knife grinder?

Yes, we have a shop here, which specializes in using Dazu kitchen knives, sharpening knives, grinding scissors and planing cutting boards as chopping boards. Master uses a kitchen knife grinder, which is not fully automatic, but it is extremely fast and can grind a knife edge in 20 seconds. We chatted, and the master said that there are too many kinds of knives, and the angle of the knife edge is not fully automatic and flexible. The master said that at most, he and his apprentice sharpened more than 600 knives for the owners in the residential property.
