Victorinox Round Diamond Steel

While a standard steel simply realigns the edge of a blade, the diamond coating on this model is abrasive. It removes a microscopic amount of metal to actually sharpen the edge while you hone, making it more effective for duller knives.

Yes, the 12-inch shaft is long enough to accommodate most standard kitchen knives, including large chef's knives and slicers. It provides ample surface area to sharpen the entire length of the blade in a single, fluid motion.

Diamond steels are quite aggressive. If you use very thin, brittle, or high-hardness Japanese steel, use a very light touch or consider a ceramic rod instead to avoid removing too much material.

Simply wipe the shaft down with a damp, non-abrasive cloth after each use to remove metal filings. Avoid putting it in the dishwasher, as this can damage the handle and the integrity of the diamond coating.

The round profile provides a consistent point of contact regardless of the angle, which is helpful for beginners. It allows you to maintain a steady sharpening angle more easily as you draw the blade across the surface.
