Wusthof Extra Wide Fine Diamond Sharpening Steel

While traditional steel rods only realign the edge of a blade, the diamond coating on this Wusthof model is abrasive. It removes a microscopic amount of metal to actually sharpen the edge, making it more effective for restoring dull knives than a standard smooth steel.

No, this tool is designed specifically for straight-edge kitchen knives. Using it on serrated blades can damage the teeth of the knife and potentially ruin the abrasive surface of the steel.

The wider surface area provides more consistent contact with the blade, which helps you maintain a steady angle throughout the sharpening stroke. This is particularly helpful for larger chef's knives or for users who are still developing their sharpening technique.

Yes, because there is no integrated angle guide, you will need to hold your knife at a consistent angle—typically between 15 and 20 degrees—while drawing it across the steel. It is best suited for users who are comfortable with, or looking to learn, manual sharpening techniques.

This sharpener is not dishwasher safe. To clean it, simply wipe the rod with a damp cloth after each use to remove metal filings, then dry it thoroughly with a clean towel to prevent any moisture buildup.
