Have now finally be able to test the knife sharpener and am thrilled. I have no idea as 0815 cook from knife grinding or sharpening my expensive knives WMF had time to be refreshed again.
Everything went RuckZuck and the knives are again as sharp as they should be ... I'm excited ... because even I can not go wrong (except the knife to pull the wrong) ...
Full marks and my recommendation for the "Pro" version
