The Work Sharp Guided Field Sharpener offers five different sharpening stages: two diamond plates (coarse for pre-sharpening and fine for honing), two ceramic rods (a large rod with three positions for fine honing and a small rod for serrated blades), and a leather strop for final polishing of the edge. It is suitable for a wide variety of blades, including outdoor knives, hunting knives, pocket knives, kitchen knives, as well as serrated tools and fishing hooks.
