The Amesser A-65 and the Cubikook CS-T01 are good sharpeners, but if you’re looking for a device that can sharpen quickly without being too harsh on the knife, the latter is the better choice.

The sharpeners are well-designed and offer great stability during sharpening, with the Amesser benefiting from its weighted base while the Cubikook, from its low working section. Both are simple to use, though the Amesser’s soft finish and ergonomic handle make it more appealing to work with.

They sport very similar working sections, with diamond-coated rods, tungsten carbide blades, and ceramic rods as abrasives. However, the Cubikook garnered better scores in all performance categories. It took less time to sharpen and removed significantly less material from the knife’s edge.

Sharpening Time to Cut a Lemon

7.6
  • Sharpening Time: 2 minutes
  • Cutting Feel: Swift and smooth

The Amesser clocked 120 seconds to restore a blunted blade back to use on a lemon. 

This is double the ideal time (60 seconds), but is still within acceptable ranges. It’s actually a few seconds faster than its identical cousin, the Kitchellence. If your kitchen knives are regularly maintained, you should be able to get them ready for a cooking session within 30 - 60 seconds on this sharpener.

  • 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.

7.0

Maximum Sharpness Achieved

8.0
  • Sharpening Time: 6 minutes
  • Sharpness Level: 8 - (Chicken breast, two swipes)

On a ripe tomato, there was no need to apply any extra effort. The tomato split cleanly without leaving behind any trace on the chopping block.

The next checkpoint—chicken breast with skin—was a slight challenge. The test knife did well on a small piece, as indicated in the video. However, on a larger piece of breast, it failed to sever the tough skin and slippery fat in one go, hence our final score of 7.0.

  • 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.

7.7

Edge Smoothness

8.7
Amesser A-65 Manual Knife Sharpener Edge Smoothness

Here are the magnified shots of the test knife after sharpening with the Amesser A-65.

The edge came out straight and well polished with minimal signs of chips, burrs, or other defects. In comparison to the other handheld sharpeners we’ve experimented with so far, this sharpener did a good job of straightening and restoring the edge. And it’s no surprise that the result is almost a mirror image of what the Kitchellence produced.

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.

6.0

Material Retention

8.0

  • Sharpening Time: 1 minute
  • Target Sharpness:

You can bet that all knife sharpeners grind away a certain amount of material from the blade to reform the edge: the only difference is the length they go to. In just one minute, the Amesser A-65 took a heavy toll on the knife’s edge, as evident by the pictures here.

We were rather astonished how this tri-stage sharpener managed to shear off almost as much metal as ones with fewer stages. Indeed, the quantity of swarf collected was somewhat similar to that produced by the Sunrise Pro and KitchenIQ.

So, if you do purchase the Amesser A-65, it’d be a good idea to use the second stage only on really dull knives. For milder cases, the ceramic rods in the third stage would suffice.

  • 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.

This sharpener is well put together and feels sturdy. Shake as hard as you might, and everything stays perfectly intact as if the whole thing is made of one solid block.

At one point, we plucked off the working section and took a quick peek inside the base. It has a metal piece attached underneath and weighs 6.44 ounces, accounting for the majority of the sharpener’s total weight.

The working section has several contact points that lock into the base and click when assembled correctly. Sadly, this part isn’t available for purchase or replacement. Once it breaks, you’ll have to toss the whole thing in the trash and get a brand-new unit.

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.

Grip

  • Material:
    ABS plastic

In general, the Amesser’s handle offers a great sense of comfort and safety. You can skip using the glove if you want to: the handle’s material feels soft and grippy, while the size is just about perfect for a good, strong grasp. The icing on the cake is a series of finger nubs running along the handle’s length.

  • 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.

Working Section

  • Abrasive:
    Diamond-coated rods, tungsten steel blades, ceramic rods
  • Mechanism:
    Pull-through
  • Sharpening Angle:
    20°

Each stage of the working section features ordinal numbering and some visual cues that display the slot’s material and function. 

The sharpening process begins with the Prep stage whose main purpose is to straighten the knife’s edge. Following that is the middle stage, used to sharpen the edge. Meanwhile, the final stage is meant for honing or giving a slightly blunt knife some light touch-ups every once in a while. 

On the whole, the Amesser A-65 should handle most types of kitchen knives.

    Coarse, Medium, Fine
  • Abrasive:
    Diamond rods, tungsten carbide blades, ceramic rods
  • Mechanism:

  • 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.

Base

  • Material:
    ABS plastic
  • Feet Type:
    Non-slip rubber base

The Amesser’s base is a checker-patterned pad that gradually tapers toward the direction of the handle. The pattern helps with creating friction and thus preventing the device from sliding across the countertop during sharpening; however, it does pick up residue and specks of dirt.

  • Material:

  • Feet Type:

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

Amesser A-65 Manual Knife Sharpener Slot Arrangement

Like the majority of handheld sharpeners, the slot structure advances from left to right. Each slot has some handy visual cues as a brief introduction to help cooks identify its function and feature. These fine prints are easy to read and they eliminate any unnecessary guesswork that may arise in the process.

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.

Insertion

9.5

The entries into the sharpening slots are just wide and deep enough to accommodate the blade properly but not comfortably. During the course of the test, there were occasional bumps here and there when positioning the knife into the slots.

We also noticed some wiggle room between the abrasives, resulting in the knife leaning and jigging sideways. This was also the reason why we sometimes had trouble keeping our draw straight, as you can see from these overhead shots.

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.

9.5

Pulling Through

9.0
Amesser A-65 Manual Knife Sharpener Pulling Through

On the whole, the abrasives were tight and solid. The first two stages actually felt a little heavy at times due to the nature of the material. 

It’s unlikely that you’ll overshoot the blade and cut into parts of the device by mistake—the plastic frame is far enough below the abrasives to prevent that.

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.

Stability on a Clean Surface

9.5
Amesser A-65 Manual Knife Sharpener Stability on Clean Surface

Save for some slight backward tilts, the Amesser barely moved at all. Thanks to its well-proportioned body, this sharpener was firm, steady, and stable. For the most part, you shouldn’t encounter any discernible problem with the device’s stability on a 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.

Stability on a Wet and Dirty Surface

Amesser A-65 Manual Knife Sharpener Stability on Dirty Surface

Prior to this test, we splashed a spoonful of oil and salt on the countertop surface to create an exaggerated mimicry of a real-life messy cooking area. The sharpener lost its footing, slipping and inching away from the original spot after just a few pulls.

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.
