It's called a mandolin.

Unless you plan to do at least 8-10 heads of cabbage at a time a
mandolin is a complete waste of time that will inflict some cuts in
you fingers as part of the process.

Give me my 10", Henkels Chef's knife and a poly cutting board.

Can trim, quarter, core and slice a head of cabbage in less than 5
minutes, and I'm not a chef, don't even play one on TV.
