Lansky Sharpeners Diamond/Carbide Tactical Sharpening Rod Black. The Lansky Tactical Sharpening Rod allows for fast blade maintenance (and in a pinch can serve as a fighting stick.) The tungsten carbide is used for quickly setting an edge and restoring a severely damaged or dull blade. The diamond rod helps restore the original geometry of the blade. For regular maintenance the diamond rod alone is sufficient. Keep your knives in top shape with a single tool - the Lansky Sharpeners Tactical Sharpening Rod.
