Amesser A-65 vs KitchenIQ 50009 Manual Sharpener Side-by-Side Comparison
Our Verdict
- Performance (50%)6.3/10
- Design (15%)9.3/10
- Ease of Use (35%)8.8/10
- Performance (50%)4.3/10
- Design (15%)8.1/10
- Ease of Use (35%)8.2/10
Though they look nothing like each other, the Amesser A-65 and the KitchenIQ 50009 are both decently-built sharpeners. The former, however, performed better in most categories and is the obvious winner here.
We appreciate the versatility offered by the KitchenIQ’s edge grip but its small size made it awkward to hold. The Amesser’s proper size and ergonomic design delivered more comfort and confidence during sharpening.
The Amesser was also the faster one between the two: Its competitor took some of the longest times we’ve experienced to sharpen a dull knife to serviceable levels. Both devices improve a blunt blade, but the Amesser to a greater extent.

Sharpening Time to Cut a Lemon
- 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: 3 minutes 35 seconds
- Cutting Feel: Swift and smooth
The KitchenIQ took 215 seconds, or more than 3 minutes to sharpen a knife to the point where it could cut through a big lemon in one single swipe. This may not sound like a terribly long time, but we generally expect faster results from handheld sharpeners. In fact, similar one-stage or two-stage devices take less than half that time to get to the same level. For example, it was 105 seconds for the Sharpal, and 65 seconds for the SunrisePro.
Maximum Sharpness Achieved
- 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: 7 (ripe tomatoes, 1 swipe)
An additional 3 minutes on the KitchenIQ took the test knife from the lemon to the ripe tomato level, and that was its peak sharpness with this device.
Though this is below what most sharpeners can achieve, at this level, the knife’s still capable of most cutting tasks, save for perhaps precision cutting and thin slicing.
We conducted this test several times over the span of six months and used the device in our kitchen throughout that time. The results were consistent, so at least we can conclude that its abrasives will take a long time to wear down.
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.
The KitchenIQ produces an ok edge with no major chips or burrs. The primary edge looks narrow, with visible horizontal grooves and tiny metal grains and fragments. The ceramic rods seem to do their job of refining the edge, making for better results compared to the Smith’s or SunrisePro.
Material Retention
- 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:
Since its tungsten carbide blades do most of the sharpening, the KitchenIQ peels off more steel from the blade than do most other multi-stage sharpeners. It produces more dust than coarse swarf, suggesting that it acts more like a grinder rather than a serious peeler. This suspicion is confirmed by the relatively fine edges it creates. This was true even when we deliberately applied more force while pulling the knife through.
Unfortunately, the extra pressure didn’t help much with improving the knife’s sharpness.

Build Quality
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 KitchenIQ deserves a shoutout for its excellent build quality despite its cheap price. The whole sharpener is solid and sturdy. Its parts all fit together seamlessly, leaving no unexpected gaps. We actually dropped it from our countertop a couple times, and it took it well. Even afterward, we didn’t observe any rattling or loose components.
The silicone grip cover was nice to the touch and comfortable to hold throughout the sharpening session.
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:Silicone
We really like the feel of the grip — it’s soft but offers good friction. It has an ergonomic shape and is connected directly to the base, thus offering great stability. Its tiny size, however, feels awkward in even smaller hands. Users with large hands will have problems finding a safe place for their fingers.
Working Section
- Levels of Sharpening:Prepare, Sharpen, Polish
- 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.
- Levels of Sharpening:Coarse, Fine
- Abrasive:Tungsten carbide blades, ceramic rods
- Mechanism:Pull through
- Sharpening Angle:20 degrees
The KitchenIQ offers two levels of sharpening. While the slots themselves are more or less the same size as those on other devices, the whole working section is rather small and doesn’t work well with larger and thicker knives.
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:Silicone
- Feet Type:Edge gripper
Not only is the layout of its working section different from most other devices, the KitchenIQ’s base is special too. It’s a thick silicone pad that covers the grip and extends all the way to the base, creating lots of friction with any flat surface. The cutout in the middle of the base forms an edge grip, allowing you to attach it to the countertop or table edge (as long as that edge is 90 degrees).

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.
The KitchenIQ employs a different slot layout than most others of its type: The coarse slot is placed further from the grip than the fine one. If you’ve used other pull-through sharpeners before, this layout will take some time to get used to. Otherwise, it’s not a problem: The slot names (Coarse and Fine) are printed on both sides of the working section, so pay a little attention and you’ll do it right. This also makes the device south-paw friendly.
Insertion
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.
You may notice that the tungsten blades in the Coarse slot have distinct corners that protrude from the plastic frame. If you use too much force or are too fast with insertion, your delicate knife edge may end up raking across one of those surfaces and risk chipping or deforming.
Also, the tiny size of the KitchenIQ means the slots are jammed together and are very close to the grip. There’s a real danger of cutting yourself if you’re not mindful while sharpening your knives.
All that being said, insertion was not challenging. We measured the actual openings and found to our surprise that they’re some of the widest among all the devices we tested (6mm).
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.
The KitchenIQ’s sturdy working section and strong base allows for steady operation. Pulling through was effortless, though it’s easy to cut into the plastic frame underneath the sharpening panels if you go too fast.
We noticed that the ‘brace’ is rather loose on this device — the sharpening rods don’t seem to grip to the blade very tightly. This contributes to the rather mediocre sharpening performance.
Stability on a 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.
With a grip and base made from one solid piece of tough silicone, the KitchenIQ stood perfectly still on a clean countertop as we pulled a knife through it. It has a low center of gravity, so regardless of the force used, the device didn’t wobble one bit.
We tried it on the countertop edge, too, which it’s designed to work on, and were happy with how well it gripped the edge.
Stability on a Wet and 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.
Like most other devices, the KitchenIQ’s silicone base couldn’t keep it in place on a dirty countertop. To its credit, the device slid but did not shake or wobble like the taller units we tested. Still, given how its grip is so close to the sharpening slots, you run the risk of cutting yourself if things slip.
The same was observed on a wet and slippery edge: no wobbling, but the silicone foot doesn’t help much in keeping it from gliding along the edge.
