As small as it is, the SunrisePro is strong, solid, and sturdy. We could tell it’s made with attention to detail and quality.
This is the aspect where the Chef’s Choice 4643 really lives up to the brand’s reputation. The sharpener is well-built, ergonomic, and a delight to work with.
The SunrisePro’s suction mechanism may take some time to get used to, and even then, it can from time to time be challenging to get it to work properly. You may also want to be mindful of the sharpening pressure or risk having your blade eaten away by the device.
The Chef’s Choice 4643 is one of the safest and most comfortable sharpeners to use. Just make sure you do not sharpen in the wrong slot.
The SunrisePro offers faster sharpening than most multi-stage devices. Unfortunately, it does so at the expense of the knife edge.
The Chef’s Choice 4643 gave a subpar performance both in speed and sharpness level. It did not shave off too much steel, but it did not really do anything to the knife’s primary edge either.
Pros & Cons
- Strong, sturdy build
- Extremely quick sharpening
- Great sharpness
- Affordable price
- Strong suction base (while it works)
- Works with 20° and 15° edges
- Compatible with serrated blades
- Grippy handle
- Neat, ergonomic overall design
- Suction base is surface-discriminatory
- It can peel off a lot of metal
- Expensive price
- Awkward slot layout
The SunrisePro wouldn’t be our first choice for a manual sharpener, but when you want sharpness and fast, you can count on it to get the job done. Unfortunately, we can’t say the same about the Chef’sChoice 4643.
The SunrisePro is a compact device with a suction cup for a base, which only works on certain surfaces. It sharpens faster than most despite (or because of?) having only one slot. The maximum sharpness level it can bring your knife to is also on par with multi-stage devices. It does, however, shave off a lot of steel from the knife’s edge, which some may find a deal-breaker.
The Chef’sChoice 4643 sports a much more substantial size and great design. It’s much safer and easier to use than the SunrisePro. The stability it offers remains unmatched by any other pull-through sharpener. Unfortunately, its sharpening discs are a failure: They create a rough edge that simply doesn’t cut it.
So as much as we love the Chef’sChoice’s robust build and design, when there’s a knife to sharpen, we’d rather go with the SunrisePro.
