The Ruixin pro V3 knife sharpening tool is, considering the price of just about 23 €, very good.

The quality of the guides could be better, but all in all, its a well designed product. Before, I was sharpening my knifes by hand on Japanese whetstones, so I am used to good quality sharpening stones. And this the one flaw the Ruixin set has. The stones begin clogging after just about 1 min. So to keep on grinding you have to constantly dress the stones to remove the metallic layer build-up. Otherwise grinding capabilities decrease so far, you will not be happy, not to mention your knifes wont get sharp. Having some experience with Boride grinding stones (usually these are used for tool finishing) to sharpen my ceramic knifes, I looked for suitable stones to sharpen my steel knifes. I wanted to try one without the need for water (oil treated) and one for wet grinding, which holds shape well. These are the ones I found most suitable:https://www.borideabrasives.com/PublicStore/product/AO,32,315.aspx (Oil treated, softer)https://www.borideabrasives.com/PublicStore/product/TH,33,316.aspx (impregnated, use with water, harder)
In germany you can get these here (I recommend the test set):

I bought the rough set TH, because for aggressive grinding its good to have stones that hold their shape well. Also tried without water, its no problem. And I bought the fine set AO, for finishing the knife and not using up to much of the softer stones.
To use these I designed the holder you find here. It's a very easy part, but now I can print one for every stone and glue them on to have the same quick change ability as in the sharpening set.
Have fun with this :-)
