Smith’s 3-in-1 Sharpener can handle all your sharpening needs. It features pre-aligned carbide blades, which are reversible and replaceable, for quick edge-setting capabilities. The Fine 750-grit Interrupted Surface Diamond Stone provides a quick razor-sharp edge on any knife or tool. A pair of specially shaped teardrop ceramic rods provide multi-use sharpening capabilities, everything from standard to serrated edges, hooks, and tools. The protective storage lid also serves as a hand guard, and the ceramic rods fit securely into a compartment in the bottom of the base for safe and easy storage.
