Chef's Choice 4643 vs. PriorityChef Manual Knife Sharpener Comparison

Overall Verdict

The PriorityChef 2-stage sharpener is a better manual sharpener than most, and it’s an easy pick over the Chef's Choice 4643.

The PriorityChef features a basic, function-oriented design, while the Chef's Choice’s design offers both stability and great comfort. Both sharpeners are sturdy, but the latter is more robust and has a much better fit and finish.

Instead of the blades and rods usually seen on other manual sharpeners, these two employ abrasive wheels, which remove considerably less knife material. However, the ones on the PriorityChef sharpened much faster and more effectively, while those on the Chef’s Choice didn’t seem to hit the knife’s edge at the right angle and delivered rather subpar results.
