It arrived earlier than expected, I'm just testing it out but it works well with 3 different knives and it came very well packaged.

It's too difficult to sharpen a knife by hand, so I bought this one, and even a beginner can sharpen it like a professional. It's very simple and sharpens perfectly without any mistakes.

Great concept. the rolling grit has ball bearings hence easy to move and the magentic knife holder holds the knife at good 15 or 20 degrees. easy to smoothly sharpen the knife with least effort.

I found it magnificent, but it only works well for medium and large knives. The sharpening edge turned out excellent, and the kit with various grits and stones, as well as the polisher, is really worth it. You don't need to apply force, just technique, and I've already sharpened several knives and they all turned out excellent! More practical than a huge kit with multiple stones.

An excellent and affordable product; local shops charge a lot more for the same quality. thank you to the seller for this high-quality item—i have already tested it. the diamond grid on the plate is excellent, and my knife is now very sharp; it only required polishing and stropping❤️

Sharpens very well. It was quick and easy. Paper test was passed, did the fine cut on a tomatoe and it was cut super finely. I'm extremely happy

For me, this idea is wonderful because I don't like sharpening with standard sharpeners. Looks stylish, suitable as a gift. Based on reviews, I bought an additional sharpening stone for 5000 grit, but 400 and 1000 grit sharpen well too. Well packed.
