Taidea pocket sharpener, double-sided

Double-sided Taidea pocket sharpener - a versatile tool to have in your backpack or pocket. Tungsten carbide (dark rods) and ceramic rods (white) for sharpening plain edges.
Start with the tungsten carbide sharpener. Put light pressure on the blade and pull it through smoothly. Too much pressure here can result in removing too much material from the cutting edge.
Finish the sharpening with the ceramic sharpener by pulling the blade through the sharpener.
