The KitchenIQ 50009 2-stage and the Zwilling 4-stage manual sharpeners have a lot more in common than their looks and prices may suggest.
Though distinctive in size, the two sharpeners share a strong, solid, sturdy build. Each has unique selling points: The former sports a compact size and an edge-gripping base, while the latter sharpens and hones at two different grind angles.
Unfortunately, neither performed particularly well in our tests. In fact, they were among the slowest and least effective sharpeners. The Zwilling did slightly better in most categories but that didn’t offer much of a consolation, especially considering its high price.
There are plenty of other manual pull-through sharpeners that can do a better job. Check out our rating tables to find the right one for you.
