2-step Messerwas?

The first, albeit somewhat half Zigen attempts resharpen kitchen knife, the success remained guilty. Do not give up, I said to myself, sharpen knives requires patience, you know that. Said and done. Have sat down and a kitchen knife 250 times drawn through the coarse side and 500 times by the fine side (I counted). With success: The knife has not become dull ... but not too sharply.

My recommendation therefore not buy. Rather spend a little more and it set something reasonable. Single stones and grindstones sets are always much better than this "pull-through eyes wiper".

Edit: If you, like me, just want to sharpen times knife from the kitchen, see my above recession. For more extensively interested, I would point to the first to comment on this review who really has to know. My gratitude.
