Build Quality
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.

There’s not much to write home about the Priority Chef’s construction and design. It’s simple and functional, and we love that it has a sturdy working section, a full, flat base, and low center of gravity. 

The biggest shortcoming seems to be the low-quality pad under the base. We’d also prefer something with more grip, though the existing one doesn’t ruin the experience.

Overall Usability Scoring

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.

With a straightforward design and slot arrangement, the learning curve is very mild with the Priority Chef. Its low center of gravity and wide, flat base offers good balance and stability. 

However, its narrow slot openings might be a bit challenging to work with. And the stainless steel grip may not be so ideal if your hands are sweaty or oily.

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 Priority Chef sharpened blades quickly while creating a decent edge and shaving off very little material from our test knife. Our test knife came out as keen as when brand-new. The device is undoubtedly one of the top performers among the ones we’ve tested, and a very well-rounded one.

Pros & Cons

  • Excellent stability 
  • Affordable price
  • Consistent sharpness
  • Solid and sturdy construction
  • Modest height, low center of gravity
  • Full, flat base
  • Gimmick-free design
  • Great edge retention
  • Small ceramic rods
  • Flaky brand label
  • Cheap base pad
  • Small slot openings


The Cubikook CS-T01 and the PriorityChef are among the best, if not the very best, manual sharpeners we’ve tested so far. The former garnered a slightly higher rating, but we’d say your choice between the two comes down to personal preference.

The Cubikook features a solid construction with a low center of gravity and a secure base. It’s stable, well-balanced, and easier to use than most. The 3-stage sharpener produces a smoother edge than the Priority Chef’s.

The latter, meanwhile, has a more modest build with some minor issues. However, its diamond-coated discs could sharpen faster than the Cubikook’s blades and rods while wasting less knife material, even though the highest level of sharpness these two sharpeners could achieve was the same (Level 8).
