KitchenIQ 50009

Cubikook CS-T01

KitchenIQ 50009 Manual vs Cubikook Manual

Overall Verdict

The KitchenIQ 50009 isn’t a bad sharpener, but it simply can’t compare to the Cubikook CS-T01.

While it does have a solid construction, an intuitive slot layout, and a base that’s more versatile than most others, the KitchenIQ 50009 is inferior where it matters the most: sharpening performance. It’s below average in speed and certainly doesn’t reach the Cubikook’s level of sharpness. The small size also makes it less comfortable and potentially more dangerous to use.

The Cubikook CS-T01 brings a decent level of sharpness to your knives in a much shorter time while being gentler on the knife edge. Its bigger size offers more comfort and confidence for most users. It’s not fault-free but the issues are mostly negligible. This sharpener is the obvious winner for us.
