Gyro-cutter, kebab knife, or shawarma slicer − whatever you call it, it’s time to make it sharp again! We can professionally sharpen to razor-sharpness most blade models for your round-blade electric knife with the same angle around the entire blade on an advanced calibrated low-speed wet stone machine to ensure no overheating to maintain blade hardness. A minimal amount of steel is removed from your round knife blades during grinding. This gives them a longer service life – benefiting both the environment and your wallet. We can sharpen round knife blades of approximately 80–140 mm in diameter.
