How to Use a Sharpening Stone


How to use a sharpening stone

Much of the success in sharpening is connected to your technique. When using a sharpening stone keep the stone’s unique requirements in mind as mentioned above:

  • Does the stone need preparation or soaking?
  • Do you need lubricant?
  • How much pressure must you apply?

When it comes to the technique you can follow this easy process or follow my step by step.

  • Place your stone on a flat surface so you can work comfortably. Put a clean cloth underneath. This will protect your work surface and prevent the stone sliding around.
  • Pick a side (coarse or fine) according to the type of sharpening you desire.
  • Apply the necessary lubricant if necessary.
  • Now slide the knife across the stone in a smooth arc. Take note:
  • Hold the knife at a 20° angle to the stone.
  • Maintain this angle so you sharpen the same piece of blade the whole time.
  • Repeat this motion a few times—usually 10—on one side. Then turn the knife around. Repeat the same motion on the other side.
  • If you started on a coarse or medium grit repeat this process on finer rated stones.

Alternative method:

Instead of sharpening the length of the blade with each swipe you can sharpen it from tip to heel. This requires you to repeat the same motions for:

  • Tip to heel on both sides
  • Heel to tip on both sides

This is necessary since you use your knife for forward and backward motions during cutting.

Which Sharpening Stone to Buy


Which Sharpening Stone to Buy

When in the process of purchasing a sharpening stone you must keep the end in sight:

  • What do you want to sharpen?
  • What will the utensil be used for?

Use the guideline above about the grit ratings.

Pick a stone which has the rating you require.

Beginners should opt for synthetic stones that allows for easy sharpening. Experienced users can try their hands at diamond sharpeners that require more skill.

Can you see how your utensils can benefit from the right sharpening stone? Remember to practice your technique for optimum results.

You may never have to purchase new knives again.
