The WÜSTHOF 9" Diamond Knife Sharpener with a diamond coating, should be used for dull or moderately sharp knives. The special shape of the diamond grit on the sharpening rod ensures exceptional sharpening of the knife blade. The result: a smooth, sharp edge. This sharpening rod has a normal grit. As these rods remove a tiny amount of metal from the knife, we recommend an additional WÜSTHOF Honing Steel for daily or weekly maintenance.

Diamond sharpening rod coarse = 180 grit (European standard); width 14mm (0.55")

• Wipe gently with a damp cloth and immediately towel-dry.
• Your diamond-coated sharpening rod is similar to sand-paper in that it will wear down over time with regular use.
