The last years we used a simple knife sharpener who walked with steel and ceramic discs for art. Looking for replacement, I came across the WMF knife sharpener. For several days, this is now in our possession and we are very satisfied with the results of large and small diameters. Two ceramic rollers which have a central groove, are under two slots available on the device. Depending on the wear of the blade, choosing the coarse or fine roller, the knife results with held vertically with light pressure repeatedly passes through the slot and the diagonally-mounted roller, thus creating an optimal sharpening with almost correct angle. We always treat the freshly sharpened knife, ending with a ceramic sharpening steel WMF. The WMF knife sharpener is much less invasive procedure with the blades in order, than its predecessor, and we look forward to a steady average of freshly sharpened blades. The WMF knife sharpener provides the opportunity with little effort to get a good result. Of course, willing and able to replace the device no Waterstones, or a professional touch.
