Cubikook Manual vs Chef'sChoice 4643 Manual Side-by-Side Comparison

Overall Verdict
At first glance, the Chef’sChoice 4643 and the Cubikook are both decent pull-through sharpeners. But when it’s time to sharpen a dull knife, the Cubikook CS-T01 wins by a mile.
Both devices feature a strong construction and a flat base that offers excellent stability. We prefer the Chef’sChoice’s ergonomic grip and minimalist base design, though its duo-angle working section can be a little confusing for first-time users. The Cubikook has a more straightforward slot layout; on the other hand, its small grip with a flaky label leaves much to be desired.
Performance-wise, the Cubikook is hands down the winner. It’s faster, sharpens to a keener level, and creates a smoother edge while removing less material from the blade. In fact, it’s one of the most effective among all the manual devices we’ve tested. The Chef’sChoice 4643’s subpar performance is simply no match.
