Step 1: Soak your Stones

Read on to get a step-by-step guide on how to use a whetstone. When working with whetstones, the first step should be to ensure that you soak your stones into the water. Please leave them in water for a few minutes before use. You will have to leave a coarse grit in water for 15 to 20 minutes, while fried grit whetstones only need a few minutes.

Step 2: Step up Your Station

Once the soaking is done, set the Whetstone on a towel on the kitchen counter. You can also keep a container with water nearby if you require water during the sharpening process. Make sure that the stone has been placed correctly.

Step 3: Sharpen the First Side

When you begin the sharpening, start from your lower-grit stone. Then, place the heel of your knife on the far edge of the stone and gently drag the knife over the surface. Keep moving the knife at the same angle so you can move towards sharpening the tip of the knife.

Step 4: Check the Sharpness

If you’re done sharpening the first side, then make sure you check for the sharpness again. Run your thumb across the edge of the blade to feel the burr from the handle to the tip. If the side is sharp enough, you can move towards the next side.

Step 5: Sharpen the Second Side

Maintain the even angle of 15 to 20 degrees as you start working on the second side. Make sure that your hand is firm but gentle at the same time. Continue repeating the strokes until the second side is also sharp enough.

Step 6: Fix the Stones

After you have sharpened both sides, your stones might develop grooves in them, obstructing the sharpening. If you want to fix the stones, use a low-grit stone fixer and push it back and forth so you can create a flat, new surface.

Step 7: Clean Up

Use the same towel to clean up your knife and stones after the sharpening process. Allow the stone to dry for a day, and then wrap up the clean stone in a good fabric cloth.

Step 8: Hone and Test Your Blade

Once you have sharpened your knife, you can hone your blade to get alignment. Once the honing is done, check the blade for sharpness as well. You can ever try slicing a tomato to see for yourself how good the knife is working after being sharpened. If you can rip through the tomato, then it means your knife is as good as new.
