The Sharpmaker offers a professional result without being difficult to use. The sharpening system is based on ceramic rods which you can place in the base plate at various angles. This determines the sharpening angle and ensures that both sides are always sharpened at the same angle. The danger of scratches on the blade is also eliminated by this system. In addition to your knives, you can also sharpen sharpen functions, tools, razor blades and hooks.
