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).

Sharpening Time to Cut a Lemon

8.8
  • Sharpening Time: 1 minutes 30 seconds
  • Cutting Feel: Swift and smooth

The Cubikook does a quick job of bringing life to a dull blade. After only 90 seconds on the device, our sandpaper-destroyed test knife could cut through a lemon with one swift draw. This placed the Cubikook in the top tier of pull-through sharpeners in terms of speed.

Most kitchen knives should see improvements after about 30 seconds on the second slot.

  • Sharpening Time: 1 minute 15 seconds
  • Cutting Feel: Swift and smooth

Our blunt test knife emerged sharp and keen after 75 seconds of sharpening with the Priority Chef. In fact, it was sharp enough to slice through a lemon in one go after just 60 seconds on the Coarse stage; the extra 15 seconds served only to refine the edge and, consequently, the cut.

Your mileage may vary depending on the conditions of your knives and the hardness of their steel. However, in most cases, you won’t need more than 30 seconds to rejuvenate a dull knife to a serviceable level.

8.0

Maximum Sharpness Achieved

8.0
  • Sharpening Time: 6 minutes
  • Sharpness Level: 8 (Chicken breast with skin, 1 swipe)

After 6 minutes of sharpening, the test knife could cut through a fresh piece of chicken breast with the skin still on. The gristly fat under the skin kept running, but we managed to sever it with a little effort. 

We tried the knife on a piece of raw beef tendon (Level 9) and it took two forced swipes, so we decided it hadn’t progressed beyond a sharpness level of 8.

  • Sharpening Time: 6 minutes
  • Sharpness Level: 8 (chicken breast with skin, 1 swipe)

Even after 6 minutes, our test knife needed two, sometimes three rather heavy swipes to cut through beef tendon. It had no trouble with chicken breast with runny skin and fat, though. Ripe tomatoes, similarly, were a piece of cake.

Since our Control knife was at sharpness Level 8 when brand new, we could say the Priority Chef sharpener can bring it back to factory sharpness after 6 minutes. Of course, you may see different results with knives that are made of particularly hard steel.

8.0

Material Retention

 Material Retention
Cubikook Material Retention
Cubikook Material Retention
  • Sharpening Time: 1 minute
  • Target Sharpness:

While effective, the Cubikook doesn’t remove a lot of material. This is one of the advantages multi-stage devices have over single-stage ones such as the Sunrise Pro. The first stage (diamond-impregnated rods) helps straighten the edge before you put it through the tungsten ‘peeler’ stage. Finally, the third, ceramic stage acts as a final honing step to leave your blade as smooth as possible. 

The benefit of single-stage devices is that they sharpen your knife quicker. That’s possible because they simply pull off more metal at a time. That means your knife will get eaten up faster, so you have the choice between quick sharpening or long overall blade life.

Priority Chef Material Retention
Priority Chef Material Retention 1
  • Sharpening Time: 1 minute
  • Target Sharpness:

For the speed and level of sharpness it can achieve, we were impressed by how little material the Priority Chef removed from the knife after one minute of sharpening. The only debris was dust and tiny chips rather than long curls of swarf, like some others. The device seems to only shave off what’s really necessary to make the edge sharp.

8.7

Edge Smoothness

7.5
Cubikook Edge Smoothness

The Cubikook creates a smooth edge. It came out looking much better than many single-stage and even multi-stage versions like Smith’s 50264 or Chef’s Choice ProntoPro. In fact, we scored this device better on the edge smoothness test than any other we’ve tested to date. It creates the straightest line with barely any visible chips, while the grooves on the primary edge were also even and narrow.

This fine edge is the result of good design choices. The device’s working section is placed low and fastened tightly to the base, which helps distribute pressure evenly against the delicate edge regardless of how much force is applied. The ceramic rods in the final stage help remove any remaining burrs or metal particles, thus minimizing edge deformities.

Priority Chef Edge Smoothness

Unlike the V-shaped abrasive blades found on most other pull-through devices, the Priority Chef’s abrasive discs create short, nearly vertical grooves along the edge — and the ceramic fine stage didn’t do much to refine them. We also detected chips and burrs — albeit very small ones — where the edge is narrowest. That suggested that the sharpening discs do not directly contact that part.

That being said, the Priority Chef still created a much finer edge than did its other disc-based cousin, the Chef’s Choice 4643. The Chef’s Choice created a secondary edge, but it left the primary edge completely untouched.

Cubikook Knife Sharpener Build Quality

The Cubikook is easily the sturdiest handheld sharpener that we’ve tested. Its working section is secured to the base using metal screws. The device is solid, and because its parts fit together tightly, it feels like it’s one piece throughout. 

The only issue is with the label. It is a strip of silicone that’s attached to the grip with glue and is starting to fall off our one-year-old device. This, however, doesn’t affect the sharpener’s functionality.

The finish is nothing to write home about, but it does ensure easy cleanup.

Priority Chef Build Quality
Priority Chef Build Quality 1

The Priority Chef has a minimalist design with stainless steel and ABS plastic parts. Although more oriented toward functionality than aesthetics, the components fit together well and sport pleasant finishes. The only complaint we have is with the base pad that’s made of a low-quality material and doesn’t fit snugly into the stainless steel frame.

7.5

Grip

7.5
Cubikook Knife Sharpener Grip
  • Material:
    ABS

This Cubikook’s grip is very simple. It’s a thin, flat handle with the brand label on top. 

It doesn’t have an ergonomic design or a velvety cover, but we’ve never had a problem maintaining a firm grip. However, we do think it could be even better if it were bulkier. 

The grip is connected to the base, forming a closed loop, which further improves the device’s stability. As a small plus, you can hang it on a rack or hook for quick access.

Priority Chef Grip
  • Material:
    Stainless steel

Unlike most other devices, the grip of the Priority Chef is basically a pipe that’s attached to the device via a plastic framework. The stainless steel is easy to clean but can be cold to the touch and feel slippery if your hand is wet or greasy. Other than that, we couldn’t find a problem with it. The low center of gravity really helps, so we never had to employ excessive force to keep the device in place.

Working Section

  • Levels of Sharpening:
    Coarse, Medium, Fine
  • Abrasive:
    Diamond rods, tungsten carbide blades, ceramic rods
  • Mechanism:
    Pull through
  • Sharpening Angle:
    20 degrees

The device has one slot with diamond rods that shape and straighten the edge, one with tungsten bars that remove burrs and small amounts of metal, and one with ceramic rods for honing. 

The working section is secured to the base with screws and is technically detachable. However, you’d have to remove the silicone feet before you can take it apart. Also, the manufacturer doesn’t seem to sell spare parts online. We find it a pity that the whole device has to be discarded once the abrasives wear down, even though the other parts are still in perfect condition.

  • Levels of Sharpening:
    Sharpen, Hone
  • Abrasive:
    Diamond-coated coarse disc, ceramic honing disc
  • Mechanism:
    Pull through
  • Sharpening Angle:
    17 degrees

The Priority Chef sharpener has a simple working section with one diamond-coated disc and one ceramic disc for sharpening and honing your knives, respectively. Each is labeled below the slot on either side — it’s equally simple whether you’re left- or right-handed.

Base

Cubikook Knife Sharpener Base
Cubikook Sharpener Base
  • Material:
    ABS plastic
  • Feet Type:
    silicone base

The Cubikook has a flat base with two silicone pads underneath to keep it in place. It isn’t particularly large, but because the device is modest in height and tapers at the top, the base area is more than enough to keep it from wobbling. We love that the design is simple but still very effective in ensuring stability.

Priority Chef Base
  • Material:
    Stainless steel
  • Feet Type:
    Sponge pad

While we love that it’s low and wide, the base is actually the Priority Chef’s least effective component. It’s a stainless steel plate housing a sponge-like pad that feels cheap and is prone to tearing. The pad adds almost no weight or friction, and we suspect that it will come apart long before anything else.

Slot Arrangement

10
Cubikook Knife Sharpener Slot Arrangement

With one single working angle and the coarseness printed at each slot, the Cubikook Chef’ Sharpener is intuitive. Swipe through the slots until the knife is sharp — you really can’t go wrong with it. The slot labels are only embossed on one side, suggesting a right-handed orientation, but it functions just as well for southpaws. You just need to remember which slot is which.

Priority Chef Slot Arrangement

The device has only two progressive slots. Their relative coarseness is embossed right underneath on both sides of the working section. That eliminates any guesswork or confusion during sharpening. Both work at the same bevel angle and are not adjustable, so the Priority Chef may not be right for all your knives.

9.5

Insertion

7.0
Cubikook Knife Sharpener Insertion

The Cubikook has some of the widest slot openings out of all the devices we tested. Granted, you can still cut into the walls if you have trembling hands or try to insert the blade too fast, but overall, insertion is pretty effortless and doesn’t require much concentration.

Priority Chef Insertion

The Priority Chef has some of the narrowest slot openings among the devices we’ve tested. While this may help keep the blade aligned, it does make inserting the knife a little stressful. 

Luckily, with a large grip and a raised plastic frame, you’re unlikely to cut your supporting hand.

9.0

Pulling Through

8.5
Cubikook Knife Sharpener Pulling Through

The Cubikook’s stability and sturdiness make pulling a blade through its slots a breeze. The smaller sharpening rods mean their cradle is rather light, but not loose — at least not when the device is still new.

Within a few months of heavy use, one of the two ceramic rods unfastened itself and started spinning whenever we pulled a blade through. This happens on both of the devices we have, so we’re not quite sure if it’s a feature or a fault in design.

We like that the sharpening slots are thin and the U-shape cutouts that frame them sit far below where the rods meet, thus staying out of the blade’s path. We can pull a whole knife through quickly, place reasonable pressure on it, even with the tip downward, and still never cut into the plastic.

Priority Chef Pulling Through

Our test knives slid through the Priority Chef with ease every single time: Both sharpening discs offer a firm and steady brace. The knife tip does cut into the U-shape frame from time to time, but because you don’t have to push downwards while pulling through, the contact is mild and should not affect the knife edge.

9.5

Stability on a Clean Surface

8.0
Cubikook Stability on a Clean Surface

The Cubikook has a low center of gravity, with its working section connected directly to its flat base. The two silicone pads underneath further aid in keeping it in place. It didn’t wobble or slip even when we deliberately applied more pressure than necessary.

Priority Chef Stability on a Clean Surface

With a low center of gravity and a full padded baseplate, the Priority Chef is well-balanced. Its anti-slip pad doesn’t exactly measure up to the name, but as long as you can maintain a relaxed grip, the device will stay in place. It may sound counterintuitive, but too much force on the grip will only make the sharpener slip more often.

8.0

Stability on a Wet and Dirty Surface

7.0
Cubikook Stability on a Wet and Dirty Surface

The Cubikook stands shoulder to shoulder with the Chef’s Choice ProntoPro in this test and beats the others by leaps and bounds. It slipped but never came close to rolling or flipping. Again, a wide base and a working section placed low to its center of gravity are the recipe for success.

Priority Chef Stability on a Wet and Dirty Surface

While the ‘anti-slip’ pad was barely effective on a spotless countertop, it was useless on one with oil and salt on it. That being said, the sharpening session was still manageable thanks to the unit’s generous footprint and modest height. Again, it seems to fare better when your grip is not too tight.
