Die erreichte Schärfe ist sehr gut. Natürlich kann man noch mehr erreichen mit den anderen Systemenm aber das nur mit einem vielfachen des Aufwands. Wer möchte kann die Messer danach auch auf einem Lederriemen mit einer feinen Schleifpaste auf Rasierschärfe bekommen. Den Tomaten- und Papiertest bestehen sie aber auch ohne hervorragend. Für sehr sehr hochwertige Messer >150€ würde ich einen anderen Schärfer einsetzen, da die Messer kaum sichtbare Spuren durch die Führung bekommen können. Für Alltagsmesser ist das aber nicht relevant. Da möchte ich nur schnell wieder scharfe Messer haben. Wichtig ist das man die Messer schön gerade und mit etwas Druck durchschiebt (wie in der Anleitung beschrieben).
