ZWILLING Accessories Diamond Sharpening Steel, 12-inch, Black/Stainless Steel(Black/Stainless Steel)

Description A diamond-coated steel will work quickly to produce a very sharp edge The flat surface provides more contact with edge to achieve the same results as a traditional rod shape but with fewer strokes Safely and easily keeps a sharp edge No assembly required German engineering Product Description UPC Code: 230173, dimension:18.75×4.5×1.75 inches Amazon.com Although steels often are touted as sharpening tools, few actually sharpen knife blades but do perform the vital task of realigning, or “resetting,” edges, which bend when contacting a cutting surface or other hard object. Because this tool's surface contains diamond dust, it's hard enough to somewhat sharpen a blade. While using this steel won't replace a professional sharpening job, which proceeds from coarse grinding to ever-finer grinding at tightly controlled angles, it will lengthen intervals between sharpenings. This steel will also perform better than a steel without diamond dust because it accomplishes the final task of a professional sharpening, which is polishing the edge to a fine point while realigning the edge. The rule is that a steel should be at least as long as the knife blade being drawn across it, and this steel's 12-inch rod handles all household knives. The steel carries a lifetime warranty against defects. –Fred Brack
