Tired of using a dull knife? Get your knives in top condition with the help of the Henckels Twin Stone Pro. This double faced stone can be used for sharpening all Zwilling J.A. Henckels stainless steel and carbon knives. Featuring both a light side for basic sharpening and a darker, coarse side to repair knicks and restore the basic shape of the edge, it is the ideal stone to perfectly hone your J.A. Henckels knives. Measures 7.5".

  • Set the whetstone into the bottom case with the grey, coarse side up. The grey side is for rough sharpening and the lighter side for fine sharpening.
  • Only fine sharpen the blade with the blue side after it has been roughly sharpened with the grey side.
  • Place the stone into the transparent bottom case. Then place the case on a flat, dry surface. The rubber feet on the bottom of the case will prevent slipping.
  • Apply a small amount of water on the surface of the stone. Completely soaking it in water is not necessary.
  • Make sure to keep the stone wet while sharpening.
  • A grey liquid will develop while sharpening. Do not wash this liquid away as it is necessary for a smooth sharpening.
  • After sharpening is complete, rinse the liquid from the surface and dry off the stone completely. Keep it in a cool and dry place away from direct sunlight.


For a double-edged knife
  • Begin sharpening on the coarse (grey) side.
  • Set the blade with the cutting edge faced toward you at an angle of 45 degrees to the length of the stone. The back of the blade should be kept at 10 to 20 degrees from the surface of the stone.
  • Place the fingers of one hand lightly on the center of the blade. While maintaining the angle, sharpen the blade by moving it back and forth using even strokes.
  • Sharpen the tip, center and then heel of the blade until a burr appears on the cutting edge.
  • Once a burr appears, turn the knife over and sharpen the other side in the same manner.
  • Turn the stone over to the lighter side and repeat steps 2 - 5. Please be aware that it is difficult to feel the burr when sharpening on the fine side. Therefore, sharpen the knife until it has reached the desired level of sharpness.
  • As a final touch, sharpen the edge a few times in a diagonal direction lightly enough to remove any remaining burrs.
  • After sharpening, remove the grinding paste by washing the knife under the tap and dry it carefully with a towel.

For knives with a one-sided edge
  • Only one side of the cutting edge needs to be sharpened, in the same manner as described above.
  • As the burr needs to be removed with one-sided edges too, turn the knife over once a burr appears, but move the knife back and forth on tip, center and heel on the non-edge side a few times only.


When the stone is worn out or becomes concave, use coarse waterproof sandpaper to even out the surface by sanding it down. You can also use a touch-up stone to flatten the surface.
