The Rozsutec whetstone is a fine whetstone for mowing with a grass blade in green grass. It its the stone to use after you have peened to a thin sharp edge as it will remove less metal than the Mailander and therefor keep your fine edge longer.

If you let your blade get too blunt you can bring the edge back with a courser Mailander Green Dragon stone then finish off with the Rozsetec for a fine edge for the lush green grass of spring....or its time to peen.
