We fell in love with the Kitchellence the moment we had it in our hands: It’s neat, simple, and strikes an excellent balance between aesthetics and functionality. We could tell the maker of it paid attention to every detail.
The Longzon looks identical to the Mueller handheld sharpener and has a much better build and design than its affordable price suggests. There’s no shoddy parts or gimmicky details — everything fits together securely and seamlessly to serve its purpose.
We also like the device’s substantial size which allows for easy sharpening of larger kitchen knives. The inclusion of the gloves is nice, though we didn’t feel the need to use them.
Its weight and design makes the Kitchellence a breeze to use: if you know how to use a knife, you will have no problem working with this device. The only mild problem is when you try to sharpen on a wet surface — but hey, it’s not hard to give your countertop a quick wipe, right?
The Longzon is straightforward, and there are visual cues on the device if you’re not sure how to use it at first glance. Its large grip and wide working section make sharpening natural and effortless. Though we think a more modest height would make it safer to use, its stability is well above average.
The Kitchellence could bring the knife to a serviceable keenness level without peeling a bunch of swarfs off the blade. However, it was slow to sharpen, which defeats the purpose of a ‘convenient sharpener’.
The Longzon 4-stage knife sharpener creates one of the finest edges we’ve seen with a device of this type. Unfortunately, the edge’s functionality doesn’t match up with its aesthetics. It only became keen after more than 3 minutes of sharpening, and a prolonged sharpening time didn’t get it much further on the sharpness scale either.
Pros & Cons
- Easy to use, intuitive design
- Soft, comfortable finish
- Extra weight near the base for stability
- Affordable price
- Included glove for added safety
- Sleek design
- Substantial, accommodative size
- Fine, smooth knife edge
- Inclusion of protective gloves
- Slot for scissors
- Tapered base
- Awkward base pad
- Tall base
- Slow sharpening
- Ineffective slot layout
Out of the two, we would choose the Kitchellence because it’s faster and more effective. However, the Longzon does have its advantages.
The Longzon removed only a minimal amount of material from the knife’s edge, and it produced a much smoother edge than the Kitchellence could. That edge was arguably the nicest we’ve seen, and we’ve tested more than a dozen manual sharpeners!
Unfortunately, the Longzon took too much time to get there, and that is a big faux pas for convenient sharpeners.
The Kitchellence wasn’t the fastest we’ve tested, either, but it certainly outspeeded the Longzon. It brought the knife further on the sharpness scale too and also did well in terms of material retention. As such, it’s the more well-rounded choice here.
