Sehr guter Schleifstein, die Qualität ist gut und mit genügend Geduld bekommt man fast jede Klinge scharf. Die Bambusschale ist rutschgehemmt und passgenau für die Schleifsteine, es ist alles ordentlich verpackt und kam ohne Beschädigungen an. Auch der Ledersteifen und die Schleifpaste sind ausgesprochen praktisch und damit lässt sich ein besonders gutes Schliffbild erzielen.ronda
My friend has purchased 3 of these for friends and family,, Must be pretty Good.
