Wusthof 10-Inch Diamond Sharpening Steel Rod - Professional Knife Sharpener for Kitchen Chefs | Perfect for Honing and Maintaining Razor-Sharp Edges on Chef Knives, Hunting Knives, and Kitchen Cutlery

Quality product, but know what you are buying. This has a very coarse grit and is great for resurrecting severely neglected knives, a job that would take FOREVER to do with a honing steel. But in my opinion, this is a companion to a good steel, not a replacement for it. I start with this product to get the dings out of the blade, then finish up with a steel to get a razor-sharp edge.
