Graef SG520 Electric Knife Sharpener in Quartz Grey

Anyone who uses their knives daily knows that even the best knife will eventually become dull. Daily meal preparation and cutting fruits and vegetables on various cutting boards, in particular, contribute to the wear and tear of the knife blade, necessitating regular sharpening. With the GRAEF SG520 knife sharpener and its diamond-coated grinding wheels, blades can be restored to excellent cutting tools thanks to the two-stage, arc-shaped blade design and precise angle guidance.

The slow-running sharpening and polishing wheels treat the material gently, ensuring a long-lasting, sharp edge. The stable 20° sharpening angle with elastomer blade guide allows for precise and safe blade sharpening, as the knife is guided by the handle, just as when cutting. This makes sharpening various types of knives quick and easy, even for beginners. The polishing stage can also be used for serrated knives.

The SG520 is therefore a reliable companion for everyday kitchen use and provides stable and long-lasting sharpness for daily cutting tasks in the kitchen.

Long live your knife!
Discover how easy it can be to keep your knives sharp and ready for use – with high-quality knife sharpeners from Graef! A sharp knife is essential for precise, effortless cutting and pure enjoyment.

Diamond grinding discs
The grinding discs of GRAEF knife sharpeners are diamond-coated. This ensures that knife blades are sharpened gently, quickly and easily. The low grinding speed prevents the blade from overheating during sharpening.

Dizor®
GRAEF knife sharpeners with Dizor technology enhance cutting performance by creating two distinct bevel angles. This forms a curved, ultra-sharp edge that stays sharp longer than a conventional V-edge.

Elastomer blade guide
The elastomer blade guide ensures precise and safe sharpening, as the knife is guided by the handle just like when cutting. Exact angle control allows quick and easy sharpening of various knife types, even without prior experience.

20° grinding angle
With a 20° grinding angle, your knife gains a strong, ultra-sharp and long-lasting multi-phase edge. The blade is ground convex. This sharpener is suitable for all household, leisure and commercial knives.
