KitchenIQ 50009 vs Longzon 4-stage Side-by-Side Comparison

Overall Verdict
The Longzon 4-stage sharpener wouldn’t be our first choice for a pull-through sharpener, but it does come out top when compared to the KitchenIQ 50009.
The KitchenIQ’s main selling point is its “edge grip”—a base that can grip onto the edge of your table or kitchen countertop. We’d give a shout out for its solid build and great fitting, too. But where actual sharpening is concerned, it’s among the slowest and least effective handheld sharpeners we’ve tested.
The Longzon itself wasn’t a top performer when it came to speed and sharpness. But it was much more forgiving of the knife’s edge and its more substantial body was easier to grip and work with. The extra slot for scissors just tops it off as the more practical option.
