Bought as a gift for my mother's knife. Which is now completely thrilled in use after a few weeks. Super processing, almost chirurguisch sharp and the wooden box makes the knives real eye-catcher. However, I recommend the purchase of a specially provided for this purpose, fine-grained grindstone since the blades should be exclusively wet sanded. Please never herumstümpern with role sharpen sharpening steel at these works of art of the blacksmith guild.
