ZWILLING Sharpening Steel

Unlike traditional smooth steel rods that only realign the edge of a blade, the 320-grit diamond coating on this rod actually removes a small amount of metal. This allows it to sharpen and refine a dull edge while you hone, making it more effective at maintaining sharpness over time.

Yes, the diamond-coated surface is suitable for both straight and serrated blades. The abrasive nature of the diamond dust allows you to effectively touch up the individual teeth of a serrated edge.

The oval shape provides a larger surface area for contact with the blade, which makes the sharpening process more efficient and stable. It offers a more consistent angle during use, making it easier to achieve a precise edge compared to a standard round rod.

This tool is not dishwasher safe and should be cleaned by hand. Simply wipe the rod with a damp cloth after use to remove any metal filings, then dry it thoroughly before storing it.

No, this model does not feature an integrated angle guide. It is designed for manual use, so you will need to maintain a consistent angle—typically between 15 and 20 degrees—by hand while drawing the blade across the rod.

The finger guard is a safety feature designed to protect your hand from accidental slips while you are drawing the knife blade down the length of the sharpening steel. It provides a physical barrier between your grip and the blade's path.
