How to Safely Sharpen a Kitchen Knife with a Whetstone

 A sharp knife is a safe knife. This method uses a combination water stone.

You will need:

• A two-sided whetstone (e.g., 1000/6000 grit)

• A bowl of water for soaking

• A tea towel

• Your dull knife

Steps:

1. Soak the Stone: Submerge the 1000-grit side of the stone in water until no more air bubbles rise (about 10-15 minutes). This lubricates the stone and prevents metal particles from clogging it.

2. Set Up: Place the stone on a damp tea towel on your counter to prevent slipping. The coarse (1000) grit side should be face up.

3. Find the Angle: This is the most critical step. The goal is a consistent 15-20 degree angle. A visual trick: place the knife flat, then tilt it halfway to vertical. That's about 15 degrees. A little more is 20. Pick an angle and lock your wrists.

4. The Motion: Place the heel of the knife at the far end of the stone. Using your off-hand, place two or three fingers on the blade's flat side, just behind the edge, to maintain pressure. Push the blade away from you across the stone, feeling the edge glide. Imagine you're trying to shave a thin slice off the top of the stone. Lead with the heel and finish with the tip in one smooth sweep.

5. Feel the Burr: Repeat this motion on one side until you feel a tiny, consistent "wire edge" or burr along the entire opposite side of the blade. You can feel this by running your thumb carefully away from the edge at a 90-degree angle. Once the burr is consistent, flip and sharpen the other side until you raise a burr back.

6. Refine and Hone: Flip the stone to the 6000-grit side, wet it, and repeat the process with lighter pressure to polish and refine the edge. Finish by stropping the knife a few times on an old leather belt or the bottom of a ceramic mug (uncoated ring) to align the microscopic teeth.
