What You Will Need;

You don’t need many things for this tutorial. Just take out the following items:

  • Diamond sharpening stones
  • Lubricant (water or oil)
  • Your knives

It is strongly recommended to sharpen your knives wet than dry. For diamond stones, you can use either water or oil, but water is the most ideal. While you may use oil, it isn’t suggested because it will not exactly help the knives.

We use oil when sharpening blades because it soaks into the stone’s pores. It stays there, which prevents clogging and keeps the stone in good condition. Using oil doesn’t provide the same benefit using diamond sharpening stones, so water is the best choice.

Here is how to use a diamond sharpening stone in making your knives good as new:

  1. Draw the Blade Down and Across: When you have positioned the knife at the correct angle, start sharpening by drawing it down and across the stone slowly. Do it in a smooth motion from the heel to the tip of the blade.
  2. Repeat the Process: Repeat step 1 several times. You will have to repeat the motion described above several times based on how dull the blades of your knives are. This way, you can ensure it will be as sharp as you want.
  3. Flip Blade to Sharpen the Other Side: When you are done on this side, flip to the other side. Start sharpening the reverse side following the same motion described in steps 1 and 2. You should also sharpen it in the same number of times to be consistent.
  4. Return to the Original Side: Next, go back to the original side. You will now sharpen the blade starting from the tip to the heel. Do this slowly in the same number of times you did before.
  5. Flip Again to the Other Side: When you are done, flip the blade to the reverse side again. Just like in step 4, sharpen the knife from the tip to heel in the same number of times for consistency.
  6. Repeat Steps 1 to 5 Using the Stone’s Fine Side: In the last step, you will be sharpening your knife using the fine side of the sharpening stone. Repeat steps 1 to 5. Remember to be consistent and on the same angle to ensure that you sharpened both sides equally.

IMPORTANT: Diamond sharpening stones come in different grits. The standard grits are extra-coarse, coarse, fine, and extra-fine. The sharpness of your blade after using the stone depends on the grit, so choose wisely.

When you first sharpen your dull knife, you will feel a burr. You will quickly feel it if you run your finger from the knife’s spine to the edge. While you sharpen from coarser diamond stone, this burr jumps from side to side.

When you feel it on both sides, start using the finer stone. As you get to the stone’s finest grit, you will feel the burr turn smaller and smaller until it is gone. If the blade cuts through paper easily, you are done sharpening your knife.
