The new series of knife sharpeners under the Magnum by Böker brand impresses with an outstanding price-performance ratio. High quality in the choice of materials and good workmanship, the water stones offer the best conditions for a very good sharpening result. Universally applicable for all types of knife blades and therefore indispensable for every household. The newly developed corundum stone has two different grain sizes. The 240 grit was designed for pre-sanding and the 1000 for fine sanding. The non-slip rubber foot stands securely on a flat surface and thus allows safe and comfortable work.
