The tool's unique design guaranties a long life. A thin sheet of perforated steel is electro-plated with a layer of diamonds and then embedded into an unbreakable plastic body. The simple design speeds up the sharpening and helps to eliminate the debris without clogging the sharpening surface.
- Real diamond, the hardest known material, shortens the sharpening time.
- A few strokes while applying only light pressure will result in a sharp edge.
- The hard mono-crystalline diamond grit is highly resistant.
- It will sharpen all hard materials such as steel, ceramics, glass, tungsten carbide, stone, etc.
