It depends on the razor steel. I refresh on a vintage YG Escher. Maybe 12 to 24 light passes. Then 7 to 12 passes with water only. Sometimes I then follow up with a vintage brown Escher with oil only, 7 to 12 light passes. I do not use my Japanese natural stones for refreshing. For edge retention I may strop on a Chromium oxide treated strop or the Hess Hair Milk Satin magic strop. This is what works for me…I’m spoiled.
