Generally whetstones are classed into 3 categories; Rough, Medium, and Fine stone.

  1. Rough Grade Whetstone is recommended at the initial stage to remove the chipped edges of the knife.
  2. Then Medium Grade Whetstone is used to bring back the edge on the blade.
  3. Finally a Fine Whetstone to bring back sharpness to the edge and restore the smooth edge on your blade.

When to sharpen your HÔTCHO?

If you can see a white line on the blade edge or it becomes obvious the sharpness has diminished then is time to sharpen your knife.

  • Whetstone has to be set on a stable platform.
  • When you use it, you must also pour a little water onto the surface of the stone.
  • Grip the handle tightly with thumb and first finger on one side and others three fingers on the other side.
  • The most important point is to get the angle correct between the blade and stone.

One of the main reasons for sharpness in a knife, is the correct angle of the blade edge.

  • A wide edge improves sharpness space, but also decreases durability.
  • The sharpening angle may be spread when you push and pull, so please keep it in mind and try to hold the knife with the same strength and angle throughout the sharpening process.
  • Please use the entire width of the stone, also move the entire edge of the blade over the stone repeatedly.
  • Then check whether there are any burrs by running your finger along the blade and away from the cutting edge, taking care not to run your finger over the edge and risk cutting yourself. If you can feel any burrs it is time to turn the blade over and repeat the process.
  • Remember to finish off using a Fine Whetstone.
  • While checking the blade, run the knife over the fine whetstone 5-10 times, but depends on blade condition.
  • Carry out the final polish on hard fabric.
