Mercer Culinary Diamond Sharpening Steel

While a standard steel rod is designed to realign the edge of a blade, the diamond-coated surface on this model actually removes a small amount of metal. This makes it more effective for maintaining sharpness and touching up dull edges rather than just realigning them.

This diamond steel is excellent for most standard kitchen knives, including German and Japanese styles. However, because it is abrasive, use it sparingly on very thin or delicate Japanese blades to avoid removing too much material over time.

You don't need to use this every time you cook. A few light passes every few weeks or whenever you feel the knife's performance slipping is usually sufficient to keep the edge in top condition.

Yes, the 12-inch length is ideal because it accommodates almost any kitchen knife, including longer chef's knives and slicers. It allows you to complete a full, smooth stroke along the entire length of the blade without having to reposition.

After use, simply wipe the rod with a damp cloth to remove any metal filings. If it gets particularly dirty, you can wash it with warm, soapy water and a soft brush, then dry it thoroughly to prevent any potential rust.
