Wiki-Artificial whetstone

  • Definition: Man-made sharpening stones created by bonding abrasive grains with a binding agent and firing them into a solid block, widely used for sharpening knives.
  • Details: Their manufacturing process ensures a uniform structure, which delivers consistent sharpening performance. Synthetic whetstones are available in a wide range of grit levels: coarse (#220–#1000) for repairing chips, medium (#1000–#3000) for routine sharpening, and fine (#4000+) for finishing.
  • Comparison: Compared to natural whetstones, synthetic ones offer predictable performance, easier availability, and lower cost, but may lack the unique feel and fine finishing ability of high-grade natural stones.
  • Practical Use: Synthetic whetstones are beginner-friendly, versatile, and cost-efficient. Before use, they should be soaked in water for 10–20 minutes until bubbling stops. Knives are sharpened at a 15–20° angle with steady pressure. After sharpening, the stone should be rinsed, dried, and stored flat. Their stability makes them ideal for home cooks and newcomers, while also serving as practical tools for professionals.
