The Lansky Tactical Sharpening Rod is just the ticket for maintaining a tactical knife. The collapsible diamond rod and tungsten carbide blades allow users to keep their knives razor sharp. The knurled aluminum handle features carbide blades at one end to take out major rolls in the cutting edge or bring back the edge on extremely dull knives. By twisting the opposite end of the housing, the diamond sharpening rod is deployed. The diamond hone is designed to take knives from working sharp back to razor sharp and is perfect for quick touch-ups on the go.
