For a fine, even resharpening, the NEW EDGE knife sharpener is equipped with high-quality, Japanese ceramic-bonded sharpening and polishing stones. In two coordinated steps, the blade is pre-sharpened and polished – the predefined angle and guiding mechanism ensure precise and controlled use at all times. The combination of sharpening stages corresponds to a 2000 grit in the first step and a 4000 grit in the second step, making it ideal for resharpening and polishing Japanese double‑bevel kitchen knives.
In the first step (Step 1 / white ceramic unit), the blade is ground. Pull the knife evenly through the sharpener about ten times. A special feature of NEW EDGE is that the blade can be moved back and forth – without applying pressure, using only the weight of the knife.
Then carefully check the sharpness of the edge – for example using a paper test or a cautious fingernail test.
In the second step (Step 2 / orange ceramic unit), the fine honing of the edge takes place. Again, pull the knife about ten times with only light pressure through the second guide back and forth to refine the sharpening pattern.
The leather strop, infused with 9µm diamond particles, allows stropping and polishing of the edge. This helps maintain an extremely fine, razor-sharp edge. While the sharpening stones are mainly used for more significant wear, the strop leather is ideal for regular blade maintenance.
To strop on leather, pull the knife backwards at a slightly flatter angle (approx. 12–13°) in slow and controlled movements across the leather. Light pressure with about 5–10 strokes per side is sufficient.
It is recommended to replace the ceramic stones of the sharpener after sharpening around 500 knives to ensure consistent performance.
