KMFS Vantaedge Integral

'The KMFS Vantaedge Integral is a pioneering manual knife sharpener developed and manufactured in the Czech Republic. It is the first device that can consistently reproduce an exact sharpening geometry without requiring the knife to be clamped in the identical position each time. Its key innovation is reverse kinematics: the system adjusts the other components relative to the knife’s current angle so the sharpening angle remains constant regardless of clamping depth.\n\nThe sharpening head offers precise, repeatable angles of 15°, 17.5°, 20° and 22.5° along the entire blade. The integral clamping device, milled from a solid block of aluminum, provides exact blade alignment, high strength and easy operation. A double clamping fixture prevents unwanted forces and conforms to the knife’s profile. The unit accepts blades up to 8 mm thick and can sharpen lengths of approximately 20–25 cm in a single clamping. Included are 240, 600 and 1000 grit diamond stones, maintenance oil and a sturdy plastic storage case.'
