Zandstra Stone refinishing Granulas

Our hardest, sharpest and longest-lasting double-sided sharpening stone crafted with industrial diamonds. The 10-by-3 inch sharpening surface quickly aligns with blades. Start with Coarse (37 microns / 400 grit) and polish with Fine (10 microns / 1200 grit) for a smooth gliding surface and minimized friction. Magnets secure the diamond plate to the base, while a screwdriver easily removes it for cleaning or replacing, delivering lifetimes of use.
