Keeping Your Knives Sharp

A sharp knife is safer than a dull one because it bites into the food rather than skidding across the surface. To maintain an edge, use a honing rod before every session to realign the metal, and have your blades professionally sharpened or use a whetstone once or twice a year to remove the dull steel.

Before you start

Consistency is your best maintenance tool.

Daily honing prevents the edge from folding over, which is why most people think their knife is dull when it is actually just misaligned. If you have to press down hard to cut a tomato skin, you are overdue for a sharpening.

  • Honing rod
  • Whetstone (1000/6000 grit)
  • Non-slip base or damp kitchen towel
The key technique

Holding the line

Whether honing or sharpening, keeping the angle between the blade and the stone constant is the only way to avoid rounding the edge. Find a 15 to 20-degree tilt and lock your wrist into that position for every single stroke.

Step by step

The method.

  1. Daily honing

    Hold the rod vertically with the tip on a cutting board. Place the heel of your blade against the rod at a 20-degree angle. Pull the knife down and across the rod toward you, ending at the tip. Repeat five times per side.

  2. Sharpening setup

    Soak your whetstone in water until bubbles stop rising. Place it on a damp towel to prevent it from sliding. Start with the coarse grit side.

  3. Building the burr

    Hold the knife at a 20-degree angle. Use two hands to maintain the tilt. Push the blade away from you along the stone, covering the entire edge from heel to tip. Repeat until you feel a tiny, jagged ridge of metal (the burr) on the opposite side of the edge.

  4. Refining the edge

    Flip to the fine grit side of the stone. Repeat the process with lighter pressure. The goal is to polish the metal and remove the burr created by the coarse stone.

Tips & troubleshooting

When it doesn't go to plan.

Tip

Never put your knives in the dishwasher; the high heat and rattling against other metal dulls edges instantly.

Tip

Store knives in a wooden block or on a magnetic strip so the blades do not clatter against other utensils in a drawer.

Tip

Test your edge by slicing a piece of paper; it should cut cleanly without tearing.

Questions

The ones that keep coming up.

How often should I sharpen on a stone?

For a home cook, once every six months to a year is usually sufficient if you are diligent about using your honing rod.

Does the material of the cutting board matter?

Yes. Avoid glass, granite, or ceramic boards, as they are harder than the steel of your knife and will ruin an edge in seconds. Stick to wood or high-density plastic.
