Key Features

  • This powerful sharpening stone is suited for fixing chipped blades and more.
  • Comes with a removable anti-slip rubber base.

Use & Care

  • Soak it in water for about 3 min prior to use so that the stone is saturated with water.
  • Sharpen your knives with it while splashing water as you work.
  • Please always use it on a flat, stable and non-slippery surface.
  • Wash it well with water after use. Let it air dry and store it away from the direct sunlight.
  • In case a part of the stone is chipped after a fall, for example, make sure to smooth out the chipped part so that the blade won't be damaged when sharpening with it.
