SG520 – The Reliable Choice for All Household Knives

Anyone who uses their knives daily knows that even the best knife will eventually become dull. The daily preparation of meals, along with cutting fruits and vegetables on different cutting boards, contributes to the wear of the blade, which is why it needs to be sharpened regularly. With the SG520 knife sharpener from GRAEF and its diamond-coated grinding wheels, blades can be restored to excellent cutting instruments thanks to the two-stage, arc-shaped blade design and precise angle guidance. The slowly rotating sharpening and polishing wheels treat the material gently, ensuring a long-lasting, sharp blade. The stable 20° sharpening angle with elastomer blade guidance allows for precise and safe blade positioning for the user, as the knife is guided at the handle just like when cutting. This makes the sharpening process easy and quick for various types of knives—even without prior knowledge. The polishing stage can also be used for serrated knives. The SG520 is therefore a reliable companion for everyday kitchen tasks, providing stable and long-lasting sharpness for daily cutting jobs in the kitchen.
