To do this, hold the knife at a 20-degree angle and gently draw it across the sharpening surface in a smooth, continuous motion, applying gentle pressure.
- Serrated Edge Sharpener: A specialized tool designed specifically for sharpening serrated knives, this device typically features a series of small, angled edges that correspond to the teeth of the blade. By rotating the knife between these edges, you can hone the serrations and restore a sharp edge.
These specialized tools and techniques can help you master the art of sharpening serrated knives.
