It does not indicate which sandpaper is on which side; the difference is not noticeable.

Perfect, it works well. Now I'll order more abrasive discs to make the edges more damaged.

Very easy to use and the blades become super sharp.

Good product, but discs are not marked. had to mark them myself. used the product photos to determine which disc is which. several discs i had to guess, because they did not have corresponding photos. the sharpener is working reasonably well, but it the wooden block was larger for the larger knives. only the gentle pressure could be used with larger knives, or they keep moving.

Double-Sided Diamond Knife Sharpening Roller

Great product, does the job.

The best sharpener I've found for someone who is an expert; I bought this one for my dad, I've already had one for over a year.

Actually a good product. However, the packaging is not optimal. The wood with the angles arrived damaged.

Good quality, easy to use.

It meets what it is supposed to do, looks of good quality, there are high expectations.

Very good 👍

Sharpens 10/10 and easy to use!

It arrived well packaged (almost as if it were fragile like glass). I will have to try it to check its effectiveness. Stay tuned for the next episode 😉

Started to use it. it does improve sharpness but not to extreme. the disks are not labled so it is hard to know what specific grain is used. please improve it by engraving or sticker
