Vulkanus is a unique patented system for knife sharpening. These are the first grinders that can sharpen both smooth and serrated blades. Every knife can be easily and in a short time sharpened almost like a razor blade. Grinding and constriction is carried out in the same patented flexible system, made from materials of high quality, which provides long service life.
