Sharpening kitchen knives on the bottom ring of a stoneware kitchen plate is not an effective or recommended method. While the ring on the bottom of some stoneware plates may feel rough or abrasive, it is not designed or intended for knife sharpening purposes. Attempting to sharpen your knives on this surface is likely to be ineffective and potentially damaging to both the knives and the plate.
Proper knife sharpening requires the use of appropriate tools, such as a sharpening stone, honing rod, or electric knife sharpener. These tools are specifically designed to remove small amounts of metal from the knife's edge, creating a sharp and precise cutting edge. They are also designed to maintain the correct angle during the sharpening process, which is crucial for preserving the knife's performance and longevity.
If you're unsure how to sharpen your kitchen knives properly, it's best to seek guidance from a professional or watch instructional videos from reputable sources. Remember, using improper sharpening methods can lead to a dulled edge, damage to the blade, and potentially pose safety hazards when using the knife for food preparation.
