SunrisePro Supreme vs Zwilling Side-by-Side Comparison
Our Verdict
- Performance (50%)7.5/10
- Design (15%)8.0/10
- Ease of Use (35%)6.3/10
- Performance (50%)4.7/10
- Design (15%)7.5/10
- Ease of Use (35%)7.8/10
The SunrisePro Supreme has its limitations, but we’d pick it over the Zwilling 4-stage manual sharpener any day.
The SunrisePro Supreme has a small, but strong and solid cylinder-shaped body with a thick suction base. It features only one sharpening slot, with tungsten carbide blades as abrasives. The sharpener is a bit tricky to use and it’s rigorous on the knife’s edge; however, it gets the job done quickly and effectively, as a convenience sharpener should.
The Zwilling boasts a much more substantial build and all the gadgetry, but struggles to turn all these extras into practical use. It’s not only slower, but also couldn’t achieve the level of sharpness produced by the SunrisePro. The only consolation was that the Zwilling produced a much finer edge, but we certainly expected a lot more for its price.

Sharpening Time to Cut a Lemon
- Sharpening Time: 1 minute 5 seconds
- Cutting Feel: Swift and smooth
The SunrisePro was one of the quickest handheld sharpeners to bring a knife from dullness to a lemon-slicing level of sharpness. It took it only 65 seconds in our tests.
In fact, merely a few swipes on the device were enough for the test knife to become serviceable. That’s 10 - 20 seconds max. Include the time to get this device out of the drawer and set it up, and your whole sharpening session would still take less than 3 minutes. If you’re in a hurry or simply detest spending time doing tedious work, the SunrisePro is no doubt one of your best bets.
- Sharpening Time: 3 minutes
- Cutting Feel: Slightly forced
The Zwilling is, sadly, one of the slower sharpeners even among its category. It took 180 seconds to sharpen a sandpaper-destroyed knife to the lemon-cutting level, and even then, the cutting motion didn’t feel completely effortless. Three minutes may feel like nothing if you’re used to working with a whetstone, but for a convenient device like this one, one would expect a much shorter time.
Maximum Sharpness Achieved
- Sharpening Time: 6 minutes
- Sharpness Level: 8 (Chicken breast with skin, 1 swipe)
This device sharpens more quickly than most others, but its sharpness plateaued at the same point: the chicken breasts. The cut was not completely effortless; however, in an older version of the test, the knife repeatedly achieved this level with ease. Taking both into account, we gave the device full marks for Level 8.
- Sharpening Time: 6 minutes
- Sharpness Level: 8 - (Chicken breast with skin, 2 swipes)
While it failed quite miserably in the speed test, the Zwilling sharpener got decent results when given more time. The test knife passed the tomato test with flying colors and could cut through the muscle and runny skin on a fresh piece of chicken breast with two light and easy swipes.
We tried it on beef tendon too, which it took two heavy strokes to sever. The device was marked as failed for this level, but we think its efforts would be sufficient for most food prep needs.
Material Retention
- Sharpening Time: 1 minute
- Target Sharpness:
The SunrisePro will shave off steel from your blade and you will see lots of swarf on the device after a heavy sharpening session. That can be disheartening, especially if yours is an expensive knife. The blade aficionados in our team almost fainted at how it completely replaced the knife’s original edge after a few months of use.
However, be gentle, don’t apply too much force, and perhaps you’ll be able to reduce unnecessary loss or at least slow down the process.
- Sharpening Time: 1 minute
- Target Sharpness:
For the sharpness level it could achieve, the Zwilling shaves off way too much steel from the knife. We couldn’t help but shudder at the long curls of swarf coming out of the Coarse slot.
Most other devices employ ceramic rods for honing the knife, so even though this function comes in the form of blades on this sharpener, we really didn’t expect the ceramic to be so harsh on the knife edge.
Edge Smoothness
With only tungsten blades, it’s no surprise that the SunrisePro doesn’t create the finest edge. The edge is narrow, rough, and toothy, with deep grooves and visible chips. All this suggests sub-par retention, meaning you’ll have to sharpen your knife more often with this device. But given that it takes a little more than a minute to get it sharp, that may not be such a problem.
Also, some users suggest using a honing strop, which we think is a great idea. Of course, that’d increase the costs.
Although the Zwilling peels a lot off the knife, we have to give it credit for the pretty edge it left. There are long and deep grooves along the edge—we could tell from the swarf alone—but overall, the edge is straight and consistent, and without visible chips or teeth.
However, with its ceramic blades chipped after only a few uses, we’re at best skeptical about the device’s ability to maintain delivery of this edge quality.

- Width:2.3" (5.8 cm)
- Height:2.6" (6.6 cm)
- Weight:2.3 oz (65 g)
At the size of a beef tomato, the SunrisePro would make a perfect on-the-go sharpener. That is if you can find a flat surface for it to stay on.
- Length:9.3" (23.6 cm)
- Width:1.7" (4.3 cm)
- Height:3.1" (7.9 cm)
- Weight:11.2 oz (318 g)
Build Quality
The SunrisePro is a well-built device, even though its affordable price may suggest otherwise. It has a dense, weighty body: the only thing left to be desired is probably the size. Its suction base is also thick and solid — definitely not the flimsy type we see on cheap household appliances.
Not a decorative piece, but it has a nice fit and finish, and is easy on the eye.
While its design leaves a lot of room for improvement, the Zwilling is overall a robust, well-built sharpener. Its body feels rigid and solid, the frame and paddings are made of high-quality materials, and every part fits together nicely, leaving no gaps.
Unfortunately, the device’s weakness is its most critical part: the ceramic sharpening blades.
Normally, ceramic is used to make honing rods on pull-through sharpeners, but on the Zwilling, it’s employed in the shape of rectangular sharpening blades with their own delicate edges. The chipping we found on those blades after only a few days of testing proved that this break from the norm was an error of judgment. Obviously, being hard but brittle, the ceramic blades couldn’t withstand a rough steel knife edge.
Grip
- Material:ABS plastic
The Sunrise Pro doesn’t have a traditional grip. The locking arm, when pushed down, triggers the suction force at the base, which keeps the device in place while you sharpen your knives. The arm is well-built, though we imagine a bigger one would be more natural to use.
- Material:ABS, EVA
The Zwilling’s grip looks and feels fancier than most other devices’, but we wish the design were more simple. The thumb holder was awkward to grasp, and both of us testers couldn’t seem to align our fingers with the finger nubs.
We also thought the space between the grip and the base to be excessive — a lower height and center of gravity would immensely improve the device’s stability.
Working Section
- Levels of Sharpening:Coarse
- Abrasive:Metal blades
- Mechanism:Pull through
- Sharpening Angle:20 degrees
The Sunrise Pro has the most simple working section among all the devices we tested. It has only one sharpening slot consisting of two metal blades forming a V, attached to a V-shaped plastic supporter.
- Levels of Sharpening:Sharpen, Polish
- Abrasive:Ceramic blades
- Mechanism:Pull through
- Sharpening Angle:15 degrees, 10 degrees
The Zwilling sharpener has a long working section, covering two types of edge angle: standard and Asian. We find the alleged grind angles of 15 and 10 degrees to be surprisingly small—standard knives typically come at 18-22 degrees and Asian knives, 13 - 15 degrees. An edge angle of 10 degrees is probably more appropriate for razors than kitchen knives.
Angles aside, we like how the working section is closer to the base than the rest of the device is. This helps lower the center of gravity even only by a little, and improves the overall balance.
SunrisePro Manual Knife Sharpener’s Base
- Material:Silicone
- Feet Type:Suction cup
We have mixed feelings about the base. It’s shockingly good when it works — the silicone absorbs some of the downward pressure from your sharpening, keeping the force steady while also suctioning hard onto the countertop, preventing shaking or slipping. However, it’s rather picky when it comes to the type of surfaces it sticks to.
Tip: If it’s a spotless surface and the suction cup is not working, spreading some water underneath it may sometimes help. We found through testing, however, that this tip can be a little hit or miss.
- Material:Plastic
- Feet Type:EVA pad
The Zwilling sharpener has a solid, flat base, with a high-quality anti-slip pad underneath. But this is yet another area where it suffers from bad design.
The base is long and narrow, which is not ideal for its considerable height. The pad only partially covers the base, leaving its border hanging in the air— the pad basically adds height while further reducing the already modest width. As a result, the device is very prone to rocking.

Slot Arrangement
The SunrisePro has only one sharpening section with two tungsten carbide blades. It’s placed on top of the device, with two plastic supporters right behind to stabilize it. There’s an arrow and the words ‘Draw this way’ engraved on the working section, so it’s almost impossible to get it wrong.
The Zwilling has more sharpening slots than most others, but its layout is straightforward. Half of the working section is for standard blades and the other half Asian, as indicated by the print underneath. The slots progress in the same order for each angle type, with their coarseness level printed on their sides.
A transparent plastic cover can be slid over the area you’re not working on, so it’s rare that you will misplace your knife while sharpening.
Insertion
On other devices where the working section consists of slots, there are wider openings that guide your blade to the V shape blades down below. The SunrisePro’s protruding sharpening blades that look like a bird’s beak are not supported by those ‘guides’, so knife insertion is slightly more difficult. Our advice is to take your time to place your knife into the middle of the slot. Do not rush or you’ll cut into the plastic frame or risk damaging the delicate edge by knocking it against the tungsten blades.
It doesn’t have the widest slot openings, but insertion is still effortless with the Zwilling. Its lowered working section and the rather spacious grip do offer a sense of confidence and safety in this regard.
Pulling Through
The amount of resistance depends on how much force you assert, but generally, you’ll have to apply quite a bit while sharpening with the SunrisePro. We tried sharpening using only the weight of the test chef’s knife and the movement was so effortless we didn’t feel the device was working.
On the other hand, use too much force and it’ll return almost a serrated edge. Also, the amount of metal you’d see left behind in the working section would be devastating.
The problem with abrasive blades is that sometimes they lose grip of the knife edge, letting it glide through untouched. The fact that its blades are made of ceramic instead of tungsten carbide as a typical sharpener’s would be doesn’t exempt the Zwilling from this issue.
The thick frame around the slots, while offering great support, does obstruct the knife tip at the end as the downward force is still in place. It gets nicked from time to time, though this doesn’t affect the knife edge or sharpness.
Stability on a Clean Surface
The SunrisePro comes with a silicone suction cup serving as a base and a locking arm to secure it. It’s awesome while it works; on the right surface, the suction cup sticksto the extent that it feels like it’s an extension of the surface.
The tricky part is that it requires a completely flat and smooth surface, such as a spotless glass or marble countertop. Also, the suction wears out after a few minutes. That can be frustrating if you’re binge sharpening your knives, but if you’re only randomly working on one, it’s not going to be a huge problem.
The Zwilling’s heavy weight (a whopping 11 ounces) and solidness couldn’t cancel out the effect of its massive height to stabilize the device. Nor did its narrow base and an even narrower anti-slip pad allow it to fare well in our test. The sharpener kept losing its balance.
Stability on a Wet and Dirty Surface
The SunrisePro’s suction cup is useless on a countertop sprayed with oil and salt. We did give it a 5 because it can be held without wobbling — the cylinder shape and its short figure help. It being very small, however, means that you have to be extra careful not to misplace your knife and cut yourself while sharpening with it.
The oil- and salt-tainted countertop only amplified all the design problems on the Zwilling. We could only keep it in place with excessive force on the grip, and so we highly recommend ensuring your countertop is dry and clean before using this sharpener.
