Ruixin Pro RX 008 sharpening a €1.- knife to razor sharpness and mirror polish.

I have a Wicked Edge which is a wonderful, amazing quality sharper that will last a lifetime but if you do not want to spend that amount of money or just occasionally sharpen a knife, you can get pretty much the same result for under €50.- with the Ruixin Pro RX008 including a full set of diamond and oil stones up to 10000 grit.
