OS3 Multifunctional 2 in 1 Knife Sharpener Orange Diamond Rod and Tungsten Carbide V-Slot for knives, for everyday use. It is certainly useful in the home environment for sharpening kitchen knives, but also in the field for leading out the edges of very sharp hunting knives. The sharpener is equipped on one side with a diamond rod with a grade of 600 for everyday sharpening and on the other side with Tungsten Carbide V-Slot restoring the sharpness of a heavily worn or damaged cutting edge. Small, the size resembling a thicker felt-tip pen, compact - easily fits in a pocket, kidney or organizer. Great for sharpening a blunt knife quickly in the field. Orange color is a feature that makes it difficult to lose equipment. Simply dropping it, it is easier to find in grass, brushwood or forest litter.
