Chef'sChoice 4643 Manual vs Kitchellence 3-Stage Manual

Overall Verdict

Both the Chef’s Choice and the Kitchellence are well-built and offer great stability during sharpening. But when it comes to results, the latter is an easy winner.

The Chef’s Choice boasts diamond-coated discs, which sounds great in theory but not so much in practice. It creates a sharp double edge, but it takes a lot longer than the Kitchellence to get there. Also, in trying to accommodate two grind angles, edge smoothness is compromised. 

The Kitchellence comes with three stages of sharpening, placed in a natural, progressive order, making it intuitive to use. Each slot features substantial rods or blades that regenerate your blade without removing too much material or destroying the edge. The device is more well-rounded and it wins in the categories that matter the most, too.
