Das einzigartige Schärfgerät für Handwerker, Haushalt und Garten

Schärft alle stumpfen Klingen und dank seiner Grösse begeistert er nicht nur Profis, welche einen Schärfer mit grösserem Griff und grösserem Schärfteil bevorzugen. Der Daumenschutz ermöglicht ein sicheres Schärfen von beispielsweise grossen Küchenmessern, Hufmesser,  Rebscheren oder Gartenscheren. Praktisch das Loch im Griff für die Aufbewahrung an einem Haken.
