Sharpener with three types of different hardness designed for effective sharpening of knives and other similar tools. The body is made of a damage-resistant material, which also functions as a water reservoir. Abrasive wheels work "wet" increasing the efficiency of sharpening. The sharpening discs are made of ceramic material, chromium corundum and aluminum oxide, depending on the intended use. This guarantees optimal pre-sharpening and fine-sharpening results. Properly selected angles of the discs, blade guiding slots and the use of water ensure effective, precise sharpening.

For preliminary and fine knife sharpening. Open the blade guard, fill the container with water, close the guard, place the blade in the appropriate guide slot. Move with smooth movements, pressing lightly.
