Ancient villagers found a cyan grinding stone in the mountains, and hundreds of years later, it was passed down from generation to generation and became a cultural habit.
Because it is a natural whetstone, it is soft, absorbs water well, and produces a good amount of sharpening fluid containing fallen or crushed abrasive grains, allowing for smooth sharpening. This medium-sized whetstone is suitable for restaurants, homes, woodworking, crafts, and gardening.
Please note: 1. Natural whetstones are made by cutting the stone directly, so there may be some small imperfections. If you are concerned about small imperfections, please purchase with caution. 2. Do not store in direct sunlight, as this may damage the whetstone. 3. The smooth side is the front, the polished side, and the rough side is the back, which is the non-slip surface.
