You can trust either the Gorilla Grip or Cubikook CS-T01 to rejuvenate your knife’s edge quickly and effectively, but if you also care about the longevity of your knives, the latter is the better choice.

These devices took exactly the same amount of time in our speed test and brought the knives to the same level of sharpness. However, the Gorilla Grip shaved off a lot more material from the test knife. The edge it produced also had more deformities than that created by the Cubikook.

Both sharpeners are decently built, but the Gorilla Grip suffers from a bumpy base that affects its balance. The Cubikook is not without flaws, but its flaky label and a rotating ceramic rod didn’t seem to have any negative effects on its sharpening performance.

Sharpening Time to Cut a Lemon

7.6
  • Sharpening Time: 1 minute 30 seconds
  • Cutting Feel: Swift and smooth

We spent 15 seconds on the Prepare slot, 1 minute on the Sharpen slot, plus 15 seconds on the Polish slot. The dull test knife came out keen enough to slice through the lemon without us applying significant force. 

If you’re in a hurry, five or six swipes on the second slot should be enough to bring a regular chef’s knife to serviceable sharpness.

  • 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.

8.0

Maximum Sharpness Achieved

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

We spent a total of 5 minutes on the tungsten carbide blades and 30 seconds on each of the remaining stages. 

The Gorilla Grip sliced through ripe tomatoes and chicken breasts with skin with minimal resistance, though the slippery chicken skin did slow it down a bit. It took two to three rather heavy swipes to sever a piece of beef tendon. However, at this sharpness level, your knives shouldn’t have a problem performing most cutting tasks.

  • 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.

5.0

Edge Smoothness

8.7
Gorilla Grip Knife Sharpener Edge Smoothness

Despite their substantial size, the ceramic rods in the Polish slot did not seem to help with smoothening and polishing the knife edge.

The aggressive removal of steel is evident on the knife’s edge — the tungsten carbide blades created small but deep waves along it. These waves should not have any negative effect on your cutting experience, but they are unsightly and will bother you if you’re a knife connoisseur. 

Also, if your knife is made of a particularly hard steel, the uneven thickness of the edge may make it more prone to chipping.

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.

5.0

Material Retention

8.0
Gorilla Grip Knife Sharpener Material Retention

  • Sharpening Time: 1 minute
  • Target Sharpness:

The Gorilla Grip is aggressive: It removed a great amount of metal off the blade during the one minute we sharpened the knife with it. The Prepare slot doesn’t seem to do too much to minimize the peeling during the next stage. 

Given how quickly the device sharpens, we don’t recommend more than a few swipes on the Sharpen slot unless your knife is really dull.

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.

Gorilla Grip Knife Sharpener  Build Quality

The Gorilla Grip has a better build than what its price suggests: It’s neat, weighted, and substantial, with parts fitting together firmly and seamlessly. Although the working section is removable, it feels like one piece with the rest of the device.

The minus points are due to its bumpy base and rubber pads, which could use better fitting and gluing. Also, the device’s exterior doesn’t feel as soft and comfy as those of its brethrens, the Kitchellence and the Amesser, but this aspect is negligible. The lack of a name or logo is surprising but doesn’t affect the overall quality in any way.

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.

In the Box

Gorilla Grip Knife Sharpener In the Box
  • Gorilla Grip sharpener
  • Care and use instructions

The Gorilla Grip sharpener comes in a neat cardboard box with detailed instructions on how to use and maintain it. The Amazon photos really don’t do it justice: The actual device looks much sleeker , and the almond color is lighter too. It’s also easy to find your favorite color among its nine color options.

  • Thank you card 

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.

Working Section

  • Mechanism:

  • Sharpening Angle:
    20 degrees

The working section of the Gorilla Grip features three sharpening slots that repair, sharpen, and polish your blade. Its sharpening rods are larger than those on other devices, such as the Cubikook or the Wamery. The working section sits securely on a rather tall, but heavy, heel and enjoys reasonable stability.

This part is removable and replaceable in theory, though we couldn’t find a place that sells it separately online.

    Coarse, Medium, Fine
  • Abrasive:

  • Mechanism:

  • Sharpening Angle:

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.

Grip

7.5
Gorilla Grip Knife Sharpener Grip
  • Material:
    Thermoplastic rubber

The grip of this device is very comfortable, thanks to its decent size, ergonomic shape, and quality material. Though not a closed loop, the handle forms a hook so that you can hang it near your countertop for quick retrieving. 

There’s little to complain about the grip, though we thought a bigger foot would be better for stability.

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.

Base

Gorilla Grip Knife Sharpener Base

  • Material:
    rubber
  • Feet Type:
    non-slip pad

The Gorilla Grip has textured rubber pads underneath it to enhance friction against the countertop. The pads don’t fit into their designated slots very well, though we think that’s more a problem of aesthetics than functionality. 

The real problem is that when standing, only a part of the bigger pad is in contact with the countertop, which means it’s not completely flat. We’re not sure if it’s the pad, the base, or the glue that attaches them that has uneven thickness, but this factor noticeably reduces the device’s stability.

  • 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.

Slot Arrangement

10
Gorilla Grip Knife Sharpener Slot Arrangement

With three working slots progressing from left to right, the Gorilla Grip doesn’t require a good memory or logical skills to work with. The function of each of the slots is also engraved right next to it, so even first-time users should have no problem working out the order.

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.

9.0

Insertion

9.5
Gorilla Grip Insertion

Its slot openings are wide and at a reasonable distance from each other, so it was easy to place the knife in the right slot with the Gorilla Grip.

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.

8.5

Pulling Through

9.0
Gorilla Grip Pulling Through

Similar to the Kitchellence and the Amesser, the Gorilla Grip’s solid body structure makes pulling the knife through its slots a breeze: It was easy for us to apply a steady force from the knife’s heel to its top. The friction was just right at every point along the blade. The knife did cut into the plastic parts of the sharpener at times, but it happened less often than with other devices.

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.

8.0

Stability on a Clean Surface

9.5
Gorilla Grip Knife Sharpener Stability on a Clean Surface

The Gorilla Grip’s base isn’t completely flat, so it wobbled as we pushed it lightly while it was placed on a table. It also has a high center of gravity and a tapered heel — big no-nos — but to some extent, the heavy weight makes up for that.

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.

7.0

Stability on a Wet and Dirty Surface

8.0
Gorilla Grip Knife Sharpener Stability on a Wet and Dirty Surface

The slippery cooking oil and salt on the countertop didn’t seem to affect the device’s stability to a great extent. Neither did the salt pose much of a challenge to the textured rubber feet.

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.
