DUAL-SIDED HONING ROD: This stainless steel knife sharpening rod features a smooth side for weekly honing and a micro-ribbed side for monthly honing, helping your knives maintain their edge and perform their best for all culinary tasks.
You've got to use conventional stones and techniques to set the edger of a knife. But, to maintain that edge this steel is the way to go. It'll bring a rolled over edge back up straight in nothing flat and keep it that way until the edge is damaged or worn to the point a fresh stone sharpening is required.
