The Cubikook Chef’ Sharpener is the no-brainer choice here. It sharpens much faster and to a slightly higher level of sharpness. The device also boasts a strong, though simple, construction that offers excellent ease of use and stability.

The only area where the Wamery outperforms the Cubikook (and all other handheld sharpeners we’ve tested to date, for that matter) is with material retention. Unfortunately, that comes at the expense of mediocre sharpness and a lengthy sharpening time. 

We would also give credits to its extra sharpening slot for scissors, but if you’re looking for a sharpener for kitchen knives, the Wamery is certainly not among our first recommendations, if at all.

Sharpening Time to Cut a Lemon

9.2
  • 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 10 seconds
  • Cutting Feel: Light and smooth

For this test, we blunted a knife with sandpaper and ran it through the Wamery. It took 70 seconds for the knife to get to the sharpness level where it can halve a lemon in one go. This effectively places the Wamery among the top group of sharpeners in terms of speed.

However, the results had not always been so satisfactory. The Wamery took significantly longer (almost 10 minutes) in our previous attempts to restore the knife’s sharpness. We found that sharpening with the knife tip pointing slightly downward helped.

8.0

Maximum Sharpness Achieved

6.0
  • 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: 7 (ripe tomatoes, 1 swipe)

As fast as it was to bring the knife to the lemon-cutting level, it didn’t go very far after that. The knife only reached Sharpness Level 7 after 6 minutes of sharpening.

You may struggle a bit with precision cutting and thin slicing, but at this level, your knife’s good for most other food prep tasks.

Material Retention

9.0
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.

  • Sharpening Time: 1 minute
  • Target Sharpness:

The coarse stage does take its toll on the knife’s edge, but the metal swarf that we collected after sharpening was rather minimal. 

Among the handheld sharpeners we put to the test, this is among the ones that yielded the smallest amount of metal residue.

8.7

Edge Smoothness

7.3
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.

There were few to no burrs on the edge.

When put under the examination of our magnifying lens, the knife’s edge looked straight. There are tiny shavings alongside and the grooves are noticeable but evenly distributed along the edge. This suggests that the honing stages did do their job, though not meticulously, to smoothen the edge.

The Cubikook comes in a nice box. Instead of an instruction booklet, the user guide is printed right on the box. We thought that was done to save paper, but then we also found a greeting card that doesn’t really say anything.

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.

Frontal overview of the sharpener.

The build of the Wamery suggests everything but top-notch craftsmanship. The sharpener is bulky but hollow and rackety. Its abrasives are a hit or miss and seem to wear out more quickly than the other devices we’ve tested. While it does look cute, the sharpener isn’t meant or built to last.

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.

  • Material:
    Rubber

The handle is spacious, which is a good thing with these sharpeners as you don’t want your gripping hand too close to where the blade goes. That being said, we think Wamery can cut back on the height while widening the base of the handle to improve balance.

The top part of the grip is covered in a soft, comfortable rubber padding, while the sides and underneath weren’t graced with the same material.

Working Section

    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.

  • Sharpening Angle:

The Wamery’s working section features a slot for shears and scissors and three for kitchen knives. For knives, you start on the tungsten carbide blades, then proceed to the diamond coated rods and ceramic rods. Without a ‘prep’ slot, we’d expected the sharpener to be harsh on the knife edge; however, that wasn’t the case.

While Wamery claims that the sharpener was designed for a wide variety of knives, it failed to mention the slots’ exact angle. We tried to reach out to the brand but so far have received no response. Certain knives have unconventional sharpening angles, so putting all of them through the same slots doesn’t seem like a good idea.

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.

  • Material:
    Synthetic silicone
  • Feet Type:
    Slip-proof padding x 2

The Wamery has a wide base, which partly makes up for its excessive height to maintain its balance. The pads underneath are soft and thin, and look cheaply made, but they do well enough to prevent the sharpener from slipping across the countertop during sharpening.

Slot Arrangement

9.0
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.

Wamery Manual Sharpener Slot Arrangement
Frontal view of the sharpener with its slots.

The Wamery has four slots, marked with numbers from 1 to 4 embossed on its stainless steel casing. Slot 1 is reserved for shears and scissors, while the rest sharpens kitchen knives.  

The knife slots progress rightward with increasing grit fineness, so it’s natural to follow through with the intended order. Our only complaint is with the lack of adequate space between the slots.

9.5

Insertion

8.0
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.

During the course of our experiment, there were times when the blade wouldn’t position itself properly in the slots. When you look at the size of the entire sharpener, Wamery has been rather economical with its abrasives slots. They were a little too shallow and narrow to accommodate the entire blade’s length comfortably.

To avoid mishaps, we had to take things slowly and re-calibrate our aim before drawing the knife through the slot. But other than that, we proceeded as normal without much to complain about.

9.0

Pulling Through

6.0
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.

The sharpening rods were solid and secure. However, the knife glided through the slots, especially the tungsten bars, at times without the slightest hint of resistance. That, of course, means the abrasives haven’t got in adequate contact with the edge to sharpen it. 

A trick we learned after multiple failures is to sharpen with the tip of the knife pointing about 20 degrees downward. Then, a frictious brace can be felt as you pull the knife through. This doesn’t work 100% of the time, but it helped enough to sharpen the knife within a reasonable time frame.

Note that the knife will cut into the plastic frame on both sides when applying this trick, but that’s better than the abrasives not working.

9.5

Stability on a Clean Surface

Stability on Clean Surface
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.

Wamery Stability on Clean Surface

Sharpeners with an elevated design are prone to rocking back and forth, even with reinforced pressure on the handle. However, the Wamery’s underside spreads over a wide surface area, which allows it to stand this test despite its rather flimsy anti-slip pads.

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.

When placed on the slippery countertop, the sharpener managed to hold itself quite well. However, be advised that there was only so much that the slip-proof pads could do. Every once in a while, the sharpener inched back and forth, albeit that was something to be expected.
