Overall Design Scoring

The Cubikook is heavily function-oriented — it skips the bells and whistles and focuses on keeping the device sturdy, stable, and effective to use.

This is the aspect where the Chef’s Choice 4643 really lives up to the brand’s reputation. The sharpener is well-built, ergonomic, and a delight to work with.

The Cubikook has a straightforward design with a flat base, a sturdy working section, and an intuitive slot arrangement. Everything supports a safe and easy sharpening experience. It’s the best handheld sharpener for those with weak or shaky hands.

The Chef’s Choice 4643 is one of the safest and most comfortable sharpeners to use. Just make sure you do not sharpen in the wrong slot.

Overall Performance Scoring

The Cubikook performed consistently well in all four categories: speed, sharpness, material retention, and edge smoothness. As pull-through sharpeners go, this one is one of the most well-rounded options.

The Chef’s Choice 4643 gave a subpar performance both in speed and sharpness level. It did not shave off too much steel, but it did not really do anything to the knife’s primary edge either.

Pros & Cons

  • Excellent stability 
  • Affordable price
  • Consistent sharpness
  • Solid and sturdy construction
  • Works with 20° and 15° edges
  • Compatible with serrated blades
  • Grippy handle
  • Neat, ergonomic overall design
  • Small ceramic rods
  • Flaky brand label
  • Expensive price
  • Awkward slot layout


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.
