Lansky Sharpeners MEDGE1: The Master\'s Edge Knife Sharpening System includes a pair of both medium (grey, 800 grit) and fine (white, 1000 grit) ceramic rods for sharpening and professional grade polishing. Also included in the system is a medium ceramic triangular rod which will sharpen all types of serrations as well as awls and fish hooks. Features three of the most common sharpening angles: 17, 20 and 25, a rubber non-slip base, easy snap in rod storage, and an integrated hand guard. The Master\'s Edge knife sharpening system works as well on hunting knives and utility knives as it does as a kitchen knife sharpener. Looks great on a counter but also stores away easily in a drawer.
