The investment has paid off fully. This device is particularly easy to use - even if you have no advanced degree is in knife sharpening. I'm totally happy! Above all, I can really see that the blade is razor-sharp and the knife not only momentarily better cuts because I actually zerfraest the blade and have ruined it, as is the case with other Schaer remote. No, the blade is really perfect erected and sharpened!
Have of course all my blade sharpened on this unit, the 'lower' knife, so the cheaper design. These were great sharp!
This device is absolutely great for people who
a. can not live without sharp knife
b. want to keep their expensive knife lifetime
c. no big clue wish of all the different Schleifstaerken, grinding angles, etc. but trotztdem really sharp knives.
The way I see it, I'm going to have to my life to buy a new knife more.
