Zwilling 4-Stage vs. PriorityChef 2-Stage Manual Sharpener: When Fewer Is Better

Overall Verdict

The Zwilling 4-stage sharpener has a stronger build and double the number of sharpening slots that the PriorityChef has. However, when put through the test, the latter proved to be superior in all the important parameters.

The Zwilling sharpener features sharpening blades, which unfortunately peeled off a lot of knife material while taking more time than most sharpeners to produce results. The blades themselves were brittle and started to chip after only a few sharpening sessions.

With the exception of  a cheap-looking base that reflects its affordable price, the PriorityChef is actually a well-designed item. More importantly, it performed well in all of our tests. This sharpener performed quickly and produced an edge that was not only sharp but also smooth while removing only a negligible amount of knife steel. It was therefore a very easy choice for us over the Zwilling.
